We MUST strive perfection in order to enter in the Heaven...even if we are not and won’t be perfect on earth...
Here are the proofs:
IN THE OLD TESTAMENT:
5:24 "And Enoch walked with God: and he was not; for God took him".
19:2 "Speak unto all the congregation of the children of Israel, and say unto them, Ye shall be holy: for I the LORD your God am holy".
26:13 "I am the LORD your God, which brought you forth out of the land of Egypt, that ye should not be their bondmen; and I have broken the bands of your yoke, and made you go upright".
6:4 "Then the presidents and princes sought to find occasion against Daniel concerning the kingdom; but they could find none occasion nor fault; forasmuch as he was faithful, neither was there any error
or fault found in him".
6:22 "My God hath sent his angel, and hath shut the lions mouths, that they have not hurt me: forasmuch as before him innocency was found in me; and also before thee, O king, have I done no hurt".
IN THE NEW TESTAMENT:
5:30 And if thy right hand offend thee, cut it off, and cast it from thee: for it is profitable for thee that one of thy members should perish, and not that thy whole body should be cast into hell.
5:48 "Be ye therefore perfect, even as your Father which is in heaven is perfect".
7:13 Enter ye in at the strait gate: for wide is the gate, and broad is the way, that leadeth to destruction, and many there be which go in thereat:
7:14 Because strait is the gate, and narrow is the way, which leadeth unto life, and few there be that find it.
11:12 And from the days of John the Baptist until now the kingdom of heaven suffereth violence, and the violent take it by force.
18:8 Wherefore if thy hand or thy foot offend thee, cut them off, and cast them from thee: it is better for thee to enter into life halt or maimed, rather than having two hands or two feet to be cast into
18:9 And if thine eye offend thee, pluck it out, and cast it from thee: it is b! etter for thee to enter into life with one eye, rather than having two eyes to be cast into hell fire.
8:35 For whosoever will save his life shall lose it; but whosoever shall lose his life for my sake and the gospels, the same shall save it.
9:43 And if thy hand offend thee, cut it off: it is better for thee to enter into life maimed, than having two hands to go into hell, into the fire that never shall be quenched:
9:44 Where their worm dieth not, and the fire is not quenched.
9:45 And if thy foot offend thee, cut it off: it is better for thee to enter halt into life, t! han having two feet to be cast into hell, into the fire that never shall be quenched:
9:46 Where their worm dieth not, and the fire is not quenched.
9:47 And if thine eye offend thee, pluck it out: it is better for thee to enter into the kingdom of God with one eye, than having two eyes to be cast into hell fire:
9:48 Where their worm dieth not, and the fire is not quenched.
9:49 For every one shall be salted with fire, and every sacrifice shall be salted with salt.
9:50 Salt is good: but if the salt have lost his saltness, wherewith will ye season it? Have salt in yourselves, and have peace one with another.
1:6 "And they were both righteous before God, walking in all the commandments and ordinances of the Lord blameless".
1:75 "In holiness and righteousness before him, all the days of our life".
12:47 "And that servant, which knew his lords will, and prepared not himself, neither did according to his will, shall be beaten with many stripes.
12:48 But he that knew not, and did commit things worthy of stripes, shall be beaten with few stripes. For unto whomsoever much is given, of him shall be much required: and to whom men have
committed much, of him they will ask the more".
13:24 Strive to enter in at the strait gate: for many, I say unto you, will seek to enter in, and shall not be able.
13:25 When once the master of the house is risen up, and hath shut to the door, and ye begin to stand without, and to knock at the door, saying, Lord, Lord, open unto us; and he shall answer and say unto
you, I know you not whence ye are:
13:26 Then shall ye begin to say, We have ea! ten and drunk in thy presence, and thou hast taught in our streets.
13:27 But he shall say, I tell you, I know you not whence ye are; depart from me, all ye workers of iniquity.
13:28 There shall be weeping and gnashing of teeth, when ye shall see Abraham, and Isaac, and Jacob, and all the prophets, in the kingdom of God, and you yourselves thrust out.
16:16 The law and the prophets were until John: since that time the kingdom of God is preached, and every man presseth into it.
8:11 She said, No man, Lord. And Jesus said unto her, Neither do I condemn thee: go, and sin no more.
10:9 I am the door: by me if any man enter in, he shall be saved, and shall go in and out, and find pasture.
14:22 Confirming the souls of the disciples, and exhorting them to continue in the faith, and that we must through much tribulation enter into the kingdom of God.
6:6 Knowing this, that our old man is crucified with him, that the body of sin might be destroyed, that henceforth we should not serve sin.
8:13 For if ye live after the flesh, ye shall die: but if ye THROUGH THE SPIRIT do mortify the deeds of the body, ye shall live.
13:14 But put ye on the Lord Jesus Christ, and make not provision for the flesh, to fulfil the lusts thereof.
9:24 Know ye not that they which run in a race run all, but one receiveth the prize? So run, that ye may obtain.
9:25 And every man that striveth for the mastery is temperate in all things. Now they do it to obtain a corruptible crown; but we an incorruptible.
9:26 I therefore so run, not as uncertainly; so fight I, not as one that beateth the air:
9:27 But I keep under my body, and bring it into subjection: lest that by any means, when I have preached to others, I myself should be a castaway.
15:58 Therefore, my beloved brethren, be ye stedfast, unmoveable, always abounding in the work of the Lord, forasmuch as ye know that your labor is not in vain in the Lord.
5:9 "Wherefore we labor, that, whether present or absent, we may be accepted of him.
5:10 For we must all appear before the judgment seat of Christ; that every one may receive the things done in his body, according to that he hath done, whether it be good or bad".
7:1 "Having therefore these promises, dearly beloved, let us cleanse ourselves from all filthiness of the flesh and spirit, perfecting holiness in the fear of God".
5:1 Stand fast therefore in the liberty wherewith Christ hath made us free, and be not entangled again with the yoke of bondage.
2:3 Thou therefore endure hardness, as a good soldier of Jesus Christ.
2:4 No man that warreth entangleth himself with the affairs of this life; that he may please him who hath chosen him to be a soldier.
2:5 And if a man also strive for masteries, yet is he not crowned, except he strive lawfully.
2:11 Dearly beloved, I beseech you as strangers and pilgrims, abstain from fleshly lusts, which war against the soul;
4:18 And if the righteous scarcely be saved, where shall the ungodly and the sinner appear?
5:8 Be sober, be vigilant; because your adversary! the devil, as a roaring lion, walketh about, seeking whom he may devour:
5:9 Whom resist stedfast in the faith, knowing that the same afflictions are accomplished in your brethren that are in the world.
1:27 Only let your conversation be as it becometh the gospel of Christ: that whether I come and see you, or else be absent, I may hear of your affairs, that ye stand fast in one spirit, with one mind striving together for the faith of the gospel;
1:28 And in nothing terrified by your adversaries: which is to them an evident token of perdition, but to you of salvation, and that of God.
1:29 For unto you it is given in the behalf of Christ, not only to believe on him, but also to suffer for his sake;
3:8 Yea doubtless, and I count all things but loss for the excellency of the knowledge of Christ Jesus my Lord: for whom I have suffered the loss of all things, and do count them but dung, that I may win
3:14 I press toward the mark for the prize of the high calling of God in Christ Jesus.
1:28 Whom we preach, warning every man, and teaching every man in all wisdom; that we may present every man perfect in Christ Jesus:
1:29 Whereunto I also labor, striving according to his working, which worketh in me mightily.
12:4 Ye have not yet resisted unto blood, striving against sin.
The Lord said in Luke
14:34 Salt is good: but if the salt have lost his savor, wherewith shall it be seasoned?
14:35 It is neither fit for the land, nor yet for the dunghill; but men cast it out. He that hath ears to hear, let him hear.
(Yes, the sanctification is a process according to: 2 Corinthians
3:18 "But we all, with open face beholding as in a glass the glory of the Lord, are changed into the same image from glory to glory, even as by the Spirit of the Lord".)
