Romans: The Power & Glory of the Gospel (B-Side) Genesis 15 // God's promise to Abram and Sarai to give them more descendents than there are stars in the sky was a truly incredibly promise - if Abram and Sarai were young and able to have children. To this old husband and wife, childless in a culture that prizes children as a blessing, God's promise seemed too good to be true. In this B-Side entry of our Romans series, Pastor Jacob Cates explains how God cannot fail to make good on the promises he makes, and guarantees his promises on his very existence as God!
