1 Thessalonians 1:3

Jesus answered and said to them, “This is the work of God, that you believe in Him whom He has sent.”

But if we hope for what we do not see, with perseverance we eagerly wait for it.

For in Christ Jesus neither circumcision nor uncircumcision means anything, but faith working through love.

But now that Timothy has come to us from you, and has brought us good news of your faith and love, and that you always remember us kindly, longing to see us just as we also long to see you,

To this end also we pray for you always, that our God will count you worthy of your calling, and fulfill all your good pleasure for goodness and the work of faith with power,

and the grace of our Lord was more than abundant, with the faith and love which are in Christ Jesus.

For God is not unrighteous so as to forget your work and the love which you have shown toward His name, in having ministered and continuing to minister to the saints.

You see that faith was working with his works, and as a result of the works, faith was perfected.
