Many have spoken or written about the grace of God. But simply put, it is God's very nature: He gives us gifts of many kinds. Things we could not earn on our own ... things to which we're not otherwise entitled. It's only because He's good, and gives good gifts to those who have sought Him. Life itself is a gift.
"If ye then, being evil, know how to give good gifts unto your children, how much more shall your Father which is in heaven give good things to them that ask him?" (Matthew 7:11)
What has God given you?
