How about this for a promise? You talk about a promise: He says, “I say to you, Ask and you shall receive; seek and you shall find; knock and it shall be opened.” What a promise! You say, “Well I asked and I didn’t receive.” I am sure you didn’t. Just about everybody in the whole room, as a Christian, could testify, “I asked and I didn’t receive” - if you’re talking about the first time you asked. What does Jesus say? He has that in the present: “Ask and keep on asking, knock and keep on knocking, seek and keep on seeking; for every one who does that, receives; every one who does that, finds; every one who does that, the door would be opened.” What an incredible promise! It means persist in keeping on, it means patience. Faith and patience.
George Mueller, a lot of you know about him, I think there was talk about his life, maybe, in some of these book reports. He took care of 1200 orphans without ever asking for any support. He says, “I live in the spirit of prayer. I pray as I walk, when I lie down and when I rise, and the answers are always coming. Tens of thousands of times have my prayers been answered. When once I am persuaded that a thing is right, I go on praying for it. The great point is never to give up till the answer comes. The great fault of the children of God is that they do not continue in prayer, they do not persevere. If they desire anything for God’s glory, they should pray until they get it.”
Well, testimonies from men like Mueller are helpful sometimes, aren’t they? Especially when those men have seen God do great things in fulfillment of His promises.
