Speaking of his apostleship Paul often spoke of God at work in him to do God's work.
2 Corinthians 3:5
Not that we are adequate in ourselves so as to consider anything as having come from ourselves, but our adequacy is from God...
1 Corinthians 15:10
But by the grace of God I am what I am, and His grace to me was not in vain. No, I worked harder than all of them—yet not I, but the grace of God that was with me.
Philippians 4:13
I can do all things through Him who strengthens me.
There are many verses like this in his epistolary. Soteriologically speaking, Paul stated,
Ephesians 2:8-10
For by grace you have been saved through faith; and that not of yourselves, it is the gift of God; not as a result of works, so that no one may boast. For we are His workmanship, created in Christ Jesus for good works, which God prepared beforehand so that we would walk in them.
And Peter expressed a similar sentiment when he wrote,
2 Peter 1:1-11
Simon Peter, a bond-servant and apostle of Jesus Christ, To those who have received a faith of the same kind as ours, by the righteousness of our God and Savior, Jesus Christ: Grace and peace be multiplied to you in the knowledge of God and of Jesus our Lord; seeing that His divine power has granted to us everything pertaining to life and godliness, through the true knowledge of Him who called us by His own glory and excellence. For by these He has granted to us His precious and magnificent promises, so that by them you may become partakers of the divine nature, having escaped the corruption that is in the world by lust. Now for this very reason also, applying all diligence, in your faith supply moral excellence, and in your moral excellence, knowledge, and in your knowledge, self-control, and in your self-control, perseverance, and in your perseverance, godliness, and in your godliness, brotherly kindness, and in your brotherly kindness, love. For if these qualities are yours and are increasing, they render you neither useless nor unfruitful in the true knowledge of our Lord Jesus Christ. For he who lacks these qualities is blind or short-sighted, having forgotten his purification from his former sins. Therefore, brethren, be all the more diligent to make certain about His calling and choosing you; for as long as you practice these things, you will never stumble; for in this way the entrance into the eternal kingdom of our Lord and Savior Jesus Christ will be abundantly supplied to you.
We walk in the good works God has provided for us to do. What God has provided must be applied, as products of the new life in Christ, not the sinful flesh.
Colossians 3:22-24
Slaves, in all things obey those who are your masters on earth, not with external service, as those who merely please men, but with sincerity of heart, fearing the Lord. Whatever you do, do your work heartily, as for the Lord rather than for men....
