What Suzy said. 8~) --
~~"But, these good deeds are not acceptable to God, because they are not motivated by a love for God.
'Hebrews 11:6, But without faith it is impossible to please Him, for he who comes to God must believe that He is, and that He is a rewarder of those who diligently seek Him.'"~~
And since all faith is given by the grace of God alone, those who've been given ears to hear and eyes to see will "be motivated" to please Him, to obey Him, to glorify His name.
Faith, repentance, praise, right living in His name -- all are the result of our regeneration, not requirements for it.
It is all of Him, and none of us. That's why it's called "mercy." We don't deserve it; it is a gift, paid in full by Christ's death on the cross and promised to us by His resurrection.
He will lose none of the sheep the Father has given Him.
