According to His Mercy -Titus 3:3-7

This is such a powerful passage...

"For we ourselves were also once foolish, disobedient, deceived, serving various lusts and pleasures, living in malice and envy, hateful and hating one another. But when the kindness and the love of God our Savior toward man appeared, not by works of righteousness which we have done, but according to His mercy He saved us, through the washing of regeneration and renewing of the Holy Spirit, whom He poured out on us abundantly through Jesus Christ our Savior, that having been justified by His grace we should become heirs according to the hope of eternal life."

The Hope of Eternal Life -Titus 1:2

In the opening of Titus 1, Paul clearly explains where he places his hope.

"in hope of eternal life which God, who cannot lie, promised before time began,"

I really like how this is written. He could have just said that God has promised eternal life, and it would still be a great promise. However, Paul also reminds the reader that God cannot lie.

If God can't lie, than His promise of eternal life is very secure.
