What do you believe when you say, “I believe in God, the Father almighty, creator of heaven and earth”?
That the eternal Father of our Lord Jesus Christ, who out of nothing created heaven and earth and everything in them, who still upholds and rules them by His eternal counsel and providence, is my God and Father because of Christ the Son.
I trust God so much that I do not doubt He will provide whatever I need for body and soul, and will turn to my good whatever adversity He sends upon me in this sad world.
God is able to do this because He is almighty God and desires to do this because He is a faithful Father.
