How do we know that we are chosen by God for salvation?

Knowing that one is chosen by God involves understanding the nature of faith as a divine gift, rather than a human achievement. In 1 Thessalonians 2:13-14, it assures us that we were chosen from the beginning for salvation through the Spirit's sanctification and belief in the truth. This belief is not a product of our striving or will but is rather obtained through God's sovereign grace. Our assurance comes when we know our faith is Christ-centered, affirming that He is our righteousness and salvation, instilling peace and joy in our hearts as we rest in His finished work.
