Mark 11:23

For verily I say unto, you, That whosoever shall say unto this mountain, Be thou removed, and be thou cast into the sea, and shall not doubt in his heart, but shall believe that those things which he saith shall come to pass, he shall have whatsoever he saith.

It was on Tuesday morning that Jesus again passed by the fig-tree with His disciples. The curse of Jesus had taken effect; the whole tree, from the roots, was withered and dead. On the evening before things had been in shadow, and therefore the apostles could easily overlook the condition of the tree, especially since their minds were likely occupied with other matters. But in the clear morning light the tree stood out from the rest so prominently that Peter remembered the incident of the day before. In a half-pleased and half-awed manner he called the Lord's attention to the result of His curse. Jesus then proceeds to give the disciples a second lesson from the miracle, one applicable to themselves and to the Christians of all times. He impresses upon them His favorite topic, next to the proclamation of the Gospel. Faith in God, trust towards God, absolute reliance upon Him is required in the kingdom of Christ. Solemnly He declares to them that such a trust has mountain-moving properties, that nothing can withstand it. But the confidence must be absolute, unqualified, not tinged by the slightest doubt. With God's command and promise before us, nothing is impossible. A Christian in most cases does not attain the object that he is striving for because there is some apprehension, some doubt in his heart as to the possibility of carrying out the plan. Such vacillating, uncertain natures defeat the ends of faith. And the tool and weapon of faith, by which it accomplishes its great deeds and wins its victories, as Jesus impresses upon His disciples, is prayer.
