Isaiah 7:10 God spoke again to Ahaz. This time he said, “Ask for a sign from your God. Ask anything. Be extravagant. Ask for the moon!” (The Message Bible)
So, this is unusual. God does not regularly go around telling people to ask for a sign. He has probably never approached you that way. But maybe, if God is beyond time, God knew that this would become an important sign, not just for the original people, but throughout history. The sign is a baby, a special baby that those who wrote the New Testament would associate with Jesus being born of a virgin. But it does beg the question, “What do you want?” What would you ask for if God approached you with such an offer? What we want often determines the course our life takes. Your deep desires may determine your occupation, your relationships, and/or your destiny. God wanted Ahaz to want to trust him? What do you want?
