Isaiah 7:1, 7-8, 10-14. When the Lord puts a burden in your heart to ask for a sign about how to solve an issue ask Him for he knows the best strategies. He is God indeed, for that reason he wants us to trust him. Just as the Lord spoke to Isaiah about our Messiah, he recommended Ahaz to request a sign because the Lord knows best. Especially when we are nervous and have no idea of what to do. God aligns our thinking to His.
