“I said earlier that one often sees a call only in retrospect. This too, strangely, is by God’s design. When God called the Israelites out of Egypt, He made an astounding statement. Remember the intense dialogue between a reluctant Moses and a beckoning God in Exodus 3? Moses finally says in exasperation, ‘But how do I know it is you who is calling us?’ This audacious challenge came even after supernatural events had provided clear evidence of God’s involvement in this plan. Who would need more than a burning bush that is engulfed by flames but is not consumed, or an audible voice that issues a call? These are not routine daily events.
To Moses’ question, God makes a remarkable reply: “After you have entered the land, you will know that it is I who has called you” (see Exodus 3:12).
1) I cannot find Exodus 3:12 – as stated by Zacharias – in the Bible. I have checked the ESV, the NIV 1984 which he is supposed to be quoting and also the NLT. Tomorrow I will check the Hebrew.
2) Nevertheless the idea seems correct. Romans 12:2 says,
“Do not conform to the pattern of this world, but be transformed by the renewing of your mind. Then you will be able to test and approve what God’s will is—his good, pleasing and perfect will.”
~ This seems to indicate that we know what God’s will is after certain things have transpired – not before. So it is quite possible that sometimes we only know God’s call on our lives after certain things have passed.
