Now the LORD attended to Sarah as He had said, and the LORD did for Sarah what He had promised. — Genesis 21:1

The Lord visited Sarah exactly as He had said He would. God is not a man that He should lie; has He said, and will He not do it? Not one word failed of all the good things the Lord had spoken. Heaven and earth will pass away, but His words will never pass away. Trust in Him at all times, pour out your heart before Him.
