Sometimes God asks us to do really strange things. God will never ask us to do anything that the Bible forbids or is unwise. Be careful because what seems wise to us may be foolish to God and vice versa. With that said everything else is up for grabs. Can you imagine what Joshua did when God told him to take the Isrealites around Jericho 7 days in a row then on the 7th march 7 times around, make a lot of noise, and then....stand there?? I bet the Jericho peeps laughed themselves to sleep every night until that last one when their "indestructable" wall fell down ha.
