I think often of the idea of a man like me standing for a God like Him. An ambassador of Christ? With mud and sweat and scruf and sin, half blind and achy all over. It's laughable, despicable really, were it not that it points to such Amazing Grace.
'Think of what you were when you were called. Not many of you were wise by human standards; not many were influential; not many were of noble birth. But God chose the foolish things of the world to shame the wise; God chose the weak things of the world to shame the strong. God chose the lowly things of this world and the despised things—and the things that are not—to nullify the things that are, so that no one may boast before Him. It is because of Him that you are in Christ Jesus, who has become for us wisdom from God—that is, our righteousness, holiness and redemption. Therefore, as it is written: “Let the one who boasts boast in the Lord.” ~Paul 1cor1
