1 Corinthians 1:26-27 (AMP)
Just look at your own calling, believers, not many (of you were considered) wise according to human standards, not many powerful or influential, not many of high and noble birth. 27) But God has selected ( for his Purpose) the foolish things of the world to shame the wise (revealing their ignorance), and God has selected (for his Purpose) the weak things of the world to shame the thing which are strong (revealing their frailty).
When we stop and consider ourselves; thinking on what God has said about us before our beginning and the assurance the Spirit gives us for the purpose; we know how unworthy. Knowing ourselves and all our short comings and still God has given us an irrevocable calling. Those things which would disqualify; God knowing us choose us for his purpose with no qualifying characteristics. Before there was anything recorded of us; we were chosen. The very things that we believe disqualify us; God has preordained too use to get his Glory. Stand steadfast; your purpose shall surely come to past.
