“Is anything too hard for the Lord? I will return to you at the appointed time next year, and Sarah will have a son.”
When God asks questions He is not looking for an answer from us to affirm His abilities and power. He asks questions so we may receive a revelation of who is His. We progressively understand who our God is through the questions he poses to us. How do you respond to His questions?
“Who do you say that I am?” (Mark 8:29) and “what have you done with what I gave you” (paraphrase from Matthew 25:14-30)
