God Is Good.
Oh, give thanks to the Lord, for He is good! For His mercy endures forever. Psalms 136:1 NKJV
We must give thanks to God for his goodness and mercy: Give thanks to the Lord, not only because he does good, but because he is good (all the streams must be traced up to the fountain), not only because he is merciful to us, but because his mercy endures for ever, and will be drawn out to those that shall come after us. We must give thanks to God, not only for that mercy which is now handed out to us here on earth, but for that which shall endure for ever in the glories and joys of heaven. - Matthew Henry
