Yes, I do recall now, that this question has been asked before. Not to long ago, I think, too. So, why are we 'afraid' to answer this question? I was reading the same Scripture this morning:
1 Thess 4v3 says 'For this is the will of God, your santification, that you should abstain from sexual immorality'.
I also read:
Galations 5:13 - 13You, my brothers, were called to be free. But do not use your freedom to indulge the sinful nature; rather, serve one another in love.
Titus 1:15-16 15To the pure, all things are pure, but to those who are corrupted and do not believe, nothing is pure. In fact, both their minds and consciences are corrupted. [b]16They claim to know God, but by their actions they deny him.[/b] They are detestable, disobedient and unfit for doing anything good.
16Be joyful always; 17pray continually; 18give thanks in all circumstances, for this is God's will for you in Christ Jesus.
19Do not put out the Spirit's fire; 20do not treat prophecies with contempt. 21Test everything. Hold on to the good. 22Avoid every kind of evil.
1 Thess. 5:16-24 23May God himself, the God of peace, sanctify you through and through. [b]May your whole spirit, soul and body be kept blameless at the coming of our Lord Jesus Christ. [/b]24The one who calls you is faithful and he will do it.
2 Thess. 1:5-10 5All this is evidence that God's judgment is right, and as a result you will be counted worthy of the kingdom of God, for which you are suffering. 6God is just: He will pay back trouble to those who trouble you 7and give relief to you who are troubled, and to us as well. This will happen when the Lord Jesus is revealed from heaven in blazing fire with his powerful angels. [b]8He will punish those who do not know God and do not obey the gospel of our Lord Jesus. [/b]9They will be punished with everlasting destruction and shut out from the presence of the Lord and from the majesty of his power [b]10on the day he comes to be glorified in his holy people and to be marveled at among all those who have believed.[/b] This includes you, because you believed our testimony to you.
1 Thess. 2:10-12 [b]10You are witnesses, and so is God, of how holy, righteous and blameless we were among you who believed. [/b]11For you know that we dealt with each of you as a father deals with his own children, 12encouraging, comforting and urging you to live lives worthy of God, who calls you into his kingdom and glory.
Galations 5:16-18 [b] 16So I say, live by the Spirit, and you will not gratify the desires of the sinful nature. 17For the sinful nature desires what is contrary to the Spirit, and the Spirit what is contrary to the sinful nature. They are in conflict with each other, so that you do not do what you want. 18But if you are led by the Spirit, you are not under law. [/b]
I guess the question to pose after this verse is - Do we, as Christians live by the Spirit? If we lived by the Spirit, then would it not be possible to be sanctified?
Galations 5:19-26 19[b]The acts of the sinful nature are obvious[/b]: sexual immorality, [b]impurity[/b] and debauchery; 20[b]idolatry[/b] and witchcraft; hatred, [b]discord, jealousy, fits of rage, selfish ambition, dissensions,[/b] factions 21and envy; drunkenness, orgies, and the like. [b]I warn you, as I did before, that those who live like this will not inherit the kingdom of God. [/b]
22But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, 23gentleness and self-control. Against such things there is no law. [b]24Those who belong to Christ Jesus have crucified the sinful nature with its passions and desires. [/b] 25Since we live by the Spirit, let us keep in step with the Spirit. 26Let us not become conceited, provoking and envying each other.
The words I highlighted in the above Scripture ([b]to do with the sinful nature[/b]), I did because those are "the most common" amongst Christians.
I have known these Scriptures for years, but I can't say that I have been like Christ in putting sin to death.
So, any thoughts?
