This was a very remarkable answer; showing that the Lord, in His human life, was the Author and Finisher of the life of faith. He did not quote His Divine power and Godhead as the cause of the withering of the fig-tree; but proceeded to give a lesson on faith, as much as to say that He had wrought the miracle by faith in His Father, and that they could do as He had done, if only they had a similar faith.
Where we get wrong in prayer is that we are so self-willed. We set ourselves to pray for things; we vow to sit up all night to bring God round to our way of thinking; we use strong cryings, tears, and protestations; we endeavor to work ourselves into a frame of faith; we think we believe; we shut the doors of our heart against the tiniest suggestion or suspicion that we do not believe. And then we are surprised if the fig-tree does not wither, or the mountain remove.
Where are we wrong? It is not hard to see. There is too much of self and the energy of the flesh in all this. We can only believe for a thing when we are in such union with God that His thought and purpose can freely flow into us, suggesting what we should pray for, and leading us to that point in which there is a perfect sympathy and understanding between us and the Divine mind. Faith is always the product of such a frame as this. Be sure that you are on the line of God's purpose. Wait for Him till the impulses of nature have subsided, and the soul is hushed and still. Then the Spirit will lead you to ask what is in the will of God to give, and you will know instantly that the Spirit intercedes within you according to the will of God.
