“who will also confirm you to the end, that you may be blameless in the day of our Lord Jesus Christ.”
who will also confirm you
The “who” here is the Lord. The word “confirm” refers to guaranteed security. God will make us stand when Christ comes again. It is not our act that confirms but God’s act. It is a result of salvation.
to the end,
God will make sure we land in heaven. This word occurred in verse 6. Corinthians have a guarantee that God will preserve them until Christ comes again. The “end” here is the coming of Christ. God will keep us saved until Christ comes, and even then, He will not charge us with anything.
Php 1:6, … being confident of this very thing, that He who has begun a good work in you will complete it until the day of Jesus Christ…
that you may be blameless
“Blameless” means chargeless or unimpeachable. This is a forensic term that connotes not to be accused. No one can lodge an indictment against us. No judge can lodge a complaint against us. That makes us exempt from accusation. No one will have the right to impeach a Christian when Christ comes, not even God. This is more than acquittal, but believers will not ever be charged with anything.
in the day of our Lord Jesus Christ
God will not bring up our sins and charge us with any sin in the revelation of Christ’s coming. He will preserve saints until the end. No one can lay a charge against us.
The Christian will stand before God without blame because of Christ.
Every Christian will be blameless when we meet Jesus face-to-face. We will be blameless because of Him (Eph 1:4; Co 1:20-24; 1 Th 5:23,24; Ju de 24). God will not arraign or accuse us. We will stand before Him free of any charge against us. It is God’s faithfulness, not our faithfulness (1:9).
Ro 8:33, Who shall bring a charge against God’s elect? It is God who justifies.
1 Pe 1:5, … who are kept by the power of God through faith for salvation ready to be revealed in the last time.
God will not hold our sin and failure in this life against us. God ensures that no charge or accusation will be laid against us when we meet Him. Jesus defeated “the accuser of the brethren.” Jesus will represent our case and cause before God. We stand perfect in Him. We share in His victory over sin on that day.
