Our Scripture reading today is Isaiah 45:22, "Look unto me, and be ye saved, all the ends of the earth: for I am God, and there is none else."
There isn't anyone outside the saving power of our God. God is able to save to the ends of the earth. As in the wilderness, all that is required is that a sinner look and live. The children of Israel in the wilderness (Numbers 21) who were sick looked at a brazen snake on a pole and were healed. Sinners today and every day look to the One Who was lifted up on the cross as the cure for spiritual death.
This is an excellent quote on this text of Scripture. “Look unto ME, is His Word, which means looking away from the church because that will save nobody; away from the preacher because he can disappoint and disillusion you; away from all outward form and ceremony. You must look off from all this to the throne and there, in your heart, see the risen, reigning Lord Jesus Christ.” (Redpath)
