Titus 3:5 sure does tell us a lot. Let's break it down, shall we?
HE saved us (Titus 3:5)
HE saved us. HE is God. HE did it! That was HIS work on the cross. HIS work cannot be duplicated.
NOT because of works done by us in righteousness (Titus 3:5)
Being a good person and doing good things or going through the motions is NOT why HE saved us.
but according to HIS own mercy (Titus 3:5)
This is about HIS mercy. HE is Holy.
by the washing of regeneration and renewal of the Holy Spirit (Titus 3:5)
It's NOT about you. It's about HIM.
Now go read verses 6 and 7 and tell me again who this is about......pray to have eyes that see and ears to hear.
