God's goodness represents everything that God is! The Goodness of God shall follow me ALL the days of my life. God didn't just start being good to you today... He has ben good to you ALL of your life. As the song says:
And all my life You have been faithful,
And all my life You have been so, so good,
With every breath that I am able,
Oh, I will sing of The Goodness of God!
