Here's a testimony I knew I would be able to give. Why? Because I took God at his word.
At the Elders and Leaders' conference a couple of weeks ago we took up not just one offering but two, and the second was in response to a prophetic word from the Lord. This word was that we were to try to be like God in his generosity, but that we would never be able to attain such a target because no matter how much we gave, God would always give more. Taking up an offering in response to such a word was fairly obvious, even though we had already just given, but another word came, through a proven prophetic ministry I know and trust: "Whatever you give, you will have back within the week."
This then presented me with a challenge. Not whether I should give; that was obvious. But how much? If I really believed that was the word of God then a "generous" amount would be very different from one where I could only give what I could spare. I took a deliberate decision to receive the prophetic word as the word of God, and stepped out in faith giving a lot more than I would have otherwise, believing that I would get it all back.
One week came and went, but both Jacqueline (who wasn't there when I gave) and I still held on to the word. If you examine prophetic time periods in the Scriptures, you will see that they are very rarely exact.
Today we received a cheque from the Inland Revenue, covering everything we had given to the Lord, plus another £80! Praise God.
