Read Titus 3 today.

Titus 3:4-8 NLT
But- When God our Savior revealed his kindness and love, [5] he saved us, not because of the righteous things we had done, but because of his mercy. He washed away our sins, giving us a new birth and new life through the Holy Spirit. [6] He generously poured out the Spirit upon us through Jesus Christ our Savior. [7] Because of his grace he declared us righteous and gave us confidence that we will inherit eternal life.
[8] This is a trustworthy saying, and I want you to insist on these teachings so that all who trust in God will devote themselves to doing good. These teachings are good and beneficial for everyone.
God’s mercy and grace. Unearned. Undeserved.
The unrighteous are declared righteous. Those dead to sin inherit eternal life.
There is great depth in the words written by Paul. The idea seems simple, yet fully comprehending the love of God is beyond us. At some point we must become like children and choose to believe.
