1 Corinthians 1:10
Now I beseech you, brethren, by the name of our Lord Jesus Christ, that ye all speak the same thing, and that there be no divisions among you; but that ye be perfectly joined together in the same mind and in the same judgment.
1 Corinthians 2:16
For who hath known the mind of the Lord, that he may instruct him? but we have the mind of Christ.
Well, the body will retain its corrupt sinful nature till it is transformed, but the mind the thinking and spiritual part is what is transformed into what is the 'mind of Christ' and be able to stand blameless and sanctified when Christ comes.
2 Timothy 2:21
If a man therefore purge himself from these,
he shall be a vessel unto honour, sanctified, and meet for the master's use, and prepared unto every good work.
1 Corinthians 1:7-8
7 So that ye come behind in no gift; waiting for the coming of our Lord Jesus Christ:
8 Who shall also confirm you unto the end,
that ye may be blameless in the day of our Lord Jesus Christ.
1 Thessalonians 5:23
And the very God of peace
sanctify you wholly; and I pray God your whole spirit and soul and body be preserved blameless unto the coming of our Lord Jesus Christ.
Romans 6:1-2
What shall we say then?
Shall we continue in sin, that grace may abound? God forbid. How shall we, that are dead to sin, live any longer therein?
2 Corinthians 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.
1 Corinthians 6:11
And such were some of you:
but ye are washed, but ye are sanctified, but ye are justified in the name of the Lord Jesus, and by the Spirit of our God.
And we see 'perfecting holiness' and 'washed', 'sanctified,,' and 'justified' through faith and the grace of God.
Well here are some statements from SOP to ponder...
"Christ is waiting with longing desire for the manifestation of Himself in His church. When the character of Christ shall be perfectly reproduced in His people, then He will come to claim them as His own" [Christ’s Object Lessons, p. 69.].
"Exact obedience is required, and those who say that it is not possible to live a perfect life, throw upon God the imputation of injustice and untruth." [Manuscript Releases, vol. 1, p. 369.].
"Therefore he (Satan) is constantly seeking to deceive the followers of Christ with his fatal sophistry that it is impossible for them to overcome." [The Great Controversy, p. 489.].
"God has plainly stated that He expects us to be perfect, and because He expects this, He has made provision for us to be partakers of the divine nature. Only thus can we gain success in striving for eternal life. The power is given by Christ." [Our High Calling, p. 213.].
"So perfect is the character represented which men must have in order to be Christ’s disciples that the infidel has said that it is not possible for any human being to attain unto it. But no less a standard must be presented by all who claim to be children of God. Infidels know not that celestial aid is provided for all who seek for it by faith. Every provision has been made in behalf of every soul who shall seek to be a partaker of the divine nature and be complete in Jesus Christ. Every defect is to be discerned and cut away from the character with an unsparing decision." [-In Heavenly Places, p. 201.].
"When our earthly labors are ended, and Christ shall come for His faithful children, we shall then shine forth as the sun in the kingdom of our Father. But before that time shall come, everything that is imperfect in us will have been seen and put away. All envy and jealousy and evil surmising and every selfish plan will have been banished from the life. "[Selected Messages, vol. 3, p. 427].
