Hebrews 11:11 (AMP)

[11]By faith even Sarah herself received the ability to conceive [a child], even [when she was long] past the normal age for it, because she considered Him who had given her the promise to be reliable and true [to His word].

: Because of faith also Sarah herself received physical power to conceive a child, even when she was long past the age for it, because she considered [God] Who had given her the promise to be reliable and trustworthy and true to His word.

What faith Sarah had! Even though she wasn’t feeling and seeing it, she believed. This is the woman that laughed, her faith wasn’t perfect, but she had a tid bit of faith and it was enough for God. God chose to heal her body, heal her mind, and she received her promise. The promise of God is your tool and evidence of the existence of Christ in your life. It will convict people’s hearts and bring them to the foot of the cross, so that they too can receive their miracle.
