In yesterday’s liturgy (EX 3:1-6, 9-12), we read of Moses who stood in the presence of God, before the burning bush . Moses was afraid and didn’t understand what God was asking of him. Sometimes we don’t know to what God is calling us, but he simply wants our availability, “Here I am, Lord.”
I suppose its like being “Open 24 hours” – being ready to do the will of God always, trusting that even though we may not “know the way” (JN 14:4-5) or think we can accomplish what God is asking, he will help us do his will. The Lord won’t abandon us to fulfill his will, for “I will be with you (EX 3:12),” says the Lord.
