He did not weaken in faith when he considered his own body, which was as good as dead...
Christian, have you looked at your body and considered it as good as dead? Have you looked at your situation and considered it hopeless? Have you looked at your circumstances and considered them bleak? So did Abraham. Nearly one hundred years of age and with a barren wife, he clung to the promise of a son. Abraham believed God and did not weaken in his faith despite being certain that the very real facts of age and infertility made the promise of a natural born son impossible.
Abraham hoped against hope and was given a son. Christian, we serve that same God. We serve the God of Abraham. The God who gives an old man and his barren wife a son. The God who sacrificed His own Son for our redemption. Why so downcast, oh my soul? Put your hope in God and in His steadfast love. Call to mind the steadfast love of the Lord and have hope.
