Now may the God of peace Himself sanctify you completely; and may your whole spirit, soul, and body be preserved blameless at the coming of our Lord Jesus Christ. He who calls you is faithful, who also will do it. (I Thessalonians 5:23-24 NKJV)
Notice three things:
1. God’s purpose is that we be sanctified completely.
2. God’s plan is that our whole spirit, soul, and body be preserved blameless.
3. God’s promise is that He will accomplish both his purpose and His plan Himself.
So we see, then, that it is God who both wills our complete sanctification and accomplishes it for us. It has to be this way since Jesus made it abundantly clear how powerless we are when he said to his disciples, “Without Me, you can do nothing.”
Paul reiterates this truth concerning God’s role in sanctifying us in Philippians 2:12-13.
Therefore, my beloved, as you have always obeyed, not as in my presence only, but now much more in my absence, work out your own salvation with fear and trembling; for it is God who works in you both to will and to do for His good pleasure.
Again, the emphasis is being placed on God’s role in our development. It is He, Himself, who is working in us to “will and to do” the things that will delight Him. It is He creating in us the power and desire to express outwardly what He has already placed inside of our born-again spirits.
Now, I am sure the question you are asking is, “What’s my part? Surely, I have to do something. Tell me.” Ok, I will.
Your part is to do what Jesus told His disciples to do when they wanted to know how to work the works of God.
Then they said to Him, “What shall we do, that we may work the works of God?” Jesus answered and said to them, “This is the work of God, that you believe in Him whom He sent.” (John 6:28-29 NKJV)
Do you want to be sanctified completely? Do you want to be preserved blameless at the coming of The Lord Jesus? Then remember, this is not your work. This is the work of God. Your part is to believe. Give Him your consent, pray as Paul prayed that He will do it; and then believe.
Child of God, He who has called you to complete sanctification is faithful, and He also will do it. Remember, the life He has called you to live is the life He supplies to you, as you pray and believe.
