Look unto Abraham… – Isaiah 51:2

For when I am weak, then I am strong. – 2 Corinthians 12:10

Let us throw ourselves more and more upon our God. If you have any work appointed you of the Lord, and it is within the compass of your strength, shame upon you if you do not perform it at once; but if it be beyond you, herein will God be glorified if you do it by His power. If there remaineth no might, wit, or wisdom in you, if you are deeply conscious of your weakness you are by this experience made the more fit to be used of the Lord, for when we are weak then are we strong. If you have confidence in God all things are possible to him that believeth. Oh, when will the church cast herself upon her God as men throw themselves into the stream when they mean to swim? They seek no longer for foothold, their foot leaves the spot whereon it rested, and they throw themselves trustfully upon the wave. The everlasting ocean of love and power is ready to upbear us: we shall swim gallantly to shore if we will but trust this blessed sea of love.

Let us begin to believe God and then let us act in daily life as if we believed Him. The just shall live by faith. Some people have a faith which is for show, a Sunday faith; faith that cannot bear the wear and tear of every day life; varnished and gilded, but with no pure metal in it. The faith of Abraham could lead strings of camels and flocks of sheep away from Haran to Canaan. His was the faith which could drive the tent-pin into a foreign soil, or roll up the canvas and seek another unknown halting place. The faith of Abraham is a faith that saith to wayfaring men, “Turn in, and I will get you a little water and wash your feet.” It is a practical, active, living, week-day, everyday faith. ~ C.H. Spurgeon
