Paul taught the deity of Christ, and I believe it means here “of the great God, and He's also our Savior.” Who is He? He's Jesus Christ, my friend. What did He do? He gave Himself for us that He might redeem us. He paid a price for us that He might redeem us not just out of sin, that's true, but redeem us "from all iniquity … and purify unto Himself a people of His own, zealous of good works." Sure God wants you to live for Him, and sure God wants good works, but He'll have to redeem you first, friends.
