One fall not equal to failure; get up and return to God.
Though a righteous man falls seven times, he will get up Pro 24:16 HCSB
Therefore Sarah laughed within herself, saying, “After I have grown old, shall I have pleasure, my lord being old also?” And the Lord said to Abraham, “Why did Sarah laugh, saying, ‘Shall I surely bear a child, since I am old?’ Is anything too hard for the Lord? At the appointed time I will return to you, according to the time of life, and Sarah shall have a son.” But Sarah denied it, saying, “I did not laugh,” for she was afraid. And He said, “No, but you did laugh!” Gen 18:12-15 NKJV
- By faith even Sarah herself received ability to conceive, even beyond the proper time of life, since she considered Him faithful who had promised. Heb 11:11 NASB
