The first act of God's Goodness is His creation of the world. Having brought the world into being by the word of His mouth, God looked at His handiwork and declared it "very good". How could it be any other than that, for God Himself, is eternally good.
God's Goodness is also seen in His spiritual creation or redemption, it is through His goodness that He provided redemption at all ...... His goodness is also seen in that He sent His Son to redeem us on the Cross.
