Scriptures are cited from the King James (Authorized) Version, unless stated otherwise.


Matthew 17: 20:


“Because of your unbelief: for verily I say unto you, If ye have faith as a grain of mustard

seed, ye shall say unto this mountain, Remove hence to yonder place; and it shall remove;

and nothing shall be impossible unto you.”


Question: This verse seems to suggest that one can accomplish anything so long as he or she

possesses enough faith. Is this the correct thought?


Answer: On two other occasions, Jesus taught His disciples the importance of increasing their

faith in God. In one instance, Peter noticed that the fig tree, cursed by Jesus the day before, had withered, to which Jesus responds (Mark 11: 22-24):


22 Have faith in God. 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. 24 Therefore I say unto you, What things soever ye desire, when ye

pray, believe that ye receive them, and ye shall have them.


In the other instance, the Apostles asked Jesus for a stronger faith (Luke 17: 5). He replies (v. 6):


“If ye had faith as a grain of mustard seed, ye might say unto this sycamine tree, Be thou

plucked up by the root, and be thou planted in the sea; and it should obey you.”


The context of Matthew 17: 20 describes a man who came to Jesus, begging Him to heal his son,

possessed by a demon. The man had previously taken his request to Jesus’ disciples, but they

could not heal him. After Jesus successfully cured the lad, His disciples enquired as to why they

had failed. Jesus’ reply is the subject of our question.


Even Small Faith Can Accomplish Much

Our Lord pinpoints the disciples’ failure as a lack of sufficient faith. He goes on to intimate that

even a small amount can work wonders, just as the mustard seed produces a large tree. As to

moving mountains or replanting trees in the sea, Jesus’ words suggest that there is a vast

potential to a living faith which remains untapped by even the most loyal of His followers.

Moses raised his staff and parted the Red Sea; Elijah prayed and ended a three-and-a-half-year

drought; and Jesus by His faith overcame the world. These are exceptional manifestations of the

power of belief.


It seems that it is not so much the moving of real mountains which is in view here. Rather the

lesson is that the power of a confident faith in God is vastly greater than most Christians can

grasp in this life. Since Jesus, the Perfect One, did not Himself hurl any real mountains into the

sea during His ministry, we may assume that this particular demonstration was not in keeping

with God’s will at the time.


From the figurative point of view, the “mountains” may be those difficulties or obstructions

along our Christian course. By exercising a steady trust in God’s ability to see us through, and

going forward in the Lord’s strength, we are to serve Him and develop the Christian graces,

overcoming difficulties otherwise impossible. Surely, we can always exercise more faith.
