Abraham was long tried, but he was richly rewarded.
The Lord tried him by delaying to fulfill His promise. Satan tried him by temptation; men tried him by jealousy, distrust, and opposition; Sarah tried him by her peevishness. But he patiently endured. He did not question God’s veracity, nor limit His power, nor doubt His faithfulness, nor grieve His love; but he bowed to divine sovereignty, submitted to infinite wisdom, and was silent under delays, waiting the Lord’s time. And so, having patiently endured, he obtained the promise.
God’s promises cannot fail of their accomplishment. Patient waiters cannot be disappointed. Believing expectation shall be realized.
Beloved, Abraham’s conduct condemns a hasty spirit, reproves a murmuring one, commends a patient one, and encourages quiet submission to God’s will and way. Remember, Abraham was tried; he patiently waited; he received the promise, and was satisfied. Imitate his example, and you will share the same blessing.

God had to bring Abraham to the end of his own strength, and to let him see that in his own body he could do nothing. He had to consider his own body as good as dead, and then take God for the whole work; and when he looked away from himself, and trusted God alone, then he became fully persuaded that what He had promised, he was able to perform. That is what God is teaching us, and He has to keep away encouraging results until we learn to trust without them, and then He loves to make His Word real in fact as well as faith.
