Sometimes God will deliver you from whatever it is that seeks to do you harm. But there are other times when, because He wants to give you a special encounter with Himself, He will not deliver you from it—but He will join you in it. Sometimes He wants you to see that even when you are in the fire, just like the bush Moses encountered, you will not be burned up. Sometimes heaven wants to join you in a bad situation instead of taking you out of it.
In Exodus 3:4-6, Moses finds himself in front of a burning bush from which God is speaking, asking first that Moses take off his shoes, as this is holy ground. So, Moses slips them off in obedience to God’s command.
If you want to know your calling, don’t go “calling-looking.” Go God-looking. God knows where He wants you, what He is calling you to do, when He wants you to do it, and how He wants it done. Therefore, if you want to find your calling, look for God. When you find God, His calling will find you.
