God’s goodness in Scripture … describes the faithful bounty that He pours out upon all His creatures. Goodness flows from the natural perfection of His deity.
God’s goodness is not the blessedness of God, but is instead something flowing from His blessedness. If He were not first infinitely blessed and complete in Himself, He could not be infinitely good and giving to us. Had He not infinite abundance in His own nature, He could not be overflowing to creatures.
