God does not lead you into wilderness to harm you. He leads you there to completely depend on Him. The dry places will bring you into a deeper intimacy with Him and you will no longer view Him as being far away. You will come to know Him in closeness and confidence. God always keeps His promises. He has the power to make them, and He has the power to fulfil them.
God gave us a sign through the parable of the fig tree. When the twigs get tender and its leaves appear, we know that summer is near. When we see revival in Israel, we know the day when the Lord is coming for us is near. This promise gives us great hope and endurance, knowing that all these will come to pass. Heaven and earth will pass away, but His words will never pass away – His promises never fail.
