Now to Him who is able to do exceedingly abundantly above all that we ask or think, according to the power that works in us. Ephesians 3:20
God has no limits; we set these according to our faith. Thus, one limits Him to such an extent that we think that He cannot do it. So, when the angel of the Lord told Sarah that she would have a child, she laughed out loud, full of disbelief. She doubted what she was listening could be possible because at her age it was impossible.
It is true. At her age, it was not possible, but his Word says: Is there something impossible for God? Sara did not know the power of God. At that time, it was revealed that her faith was not strong enough to believe in what He does.
Just like Sarah, many have a weak faith that does not allow them to believe in the power of God. They live without hope, expecting nothing whatsoever, because they have allowed their own concepts to put limits to the Lord’s moving. Believe God above all and, when thoughts want to set limits, declare the written Word. Then He will move as He did with Sarah and Abraham.
