When Jesus said faith the size of a mustard seed was all that is needed to cast a mountain into the sea, He was not talking about natural faith which we all have. He was talking about the kind that comes from God. He often told the disciples that they had little faith. And that some, who tended to be Gentiles, had great faith.

The God kind of faith believes God, and that is what pleases God.

The faith He was talking about is so powerful it can move a mountain, but they didn’t have that kind of faith. He wasn’t telling them that if they only had a little they could do big things. He was telling them what the God kind of faith was.

Mark 11:21 And remembering, Peter said to Him, Rabbi, behold, the fig tree which You cursed has withered. 22 And answering, Jesus said to them, Have faith of God. 23 For truly I say to you, Whoever says to this mountain, Be taken up and be thrown into the sea, and does not doubt in his heart, but believes that what he says will happen, it will be to him, whatever he says.(Green’s Literal Translation)

Please notice that the literal translation of verse 22 above says to have faith of God, not in God (vs 22). The word for God, theou/theos, is the modifier of the noun, belief/faith, pistos. This could indicate having either faith that comes from God, or faith directed toward God, or both, like love. We only love His way because He loved us first and put it in our hearts by the Holy Spirit.

In other passages, the faith of God is in the sense of His faithfulness to do something. That is, we can trust Him to do it. Pistos means trust, as to be persuaded of His trustworthiness. This is faith toward God, or the God kind of faith.

Paul talks about having all faith and references Jesus’ statement: 1Corinthians 13:2 And though I have the gift of prophecy, and understand all mysteries, and all knowledge; and though I have all (any, every, the whole) faith, so that I could remove mountains, and have not charity, I am nothing.

The word for “all,” used in this passage, means “any, every, the whole”.

This indicates that we may not have “all” but that we possibly could.

He goes on to say that we only know part of the whole in this life, but one day we will see Him face to ­face and will then know the whole. Until then we have to renew our minds in order to walk in faith.

Romans 12:2 And be not conformed to this age, but be transformed by the renewing of your mind, in order to prove by you what is the good and pleasing and perfect will of God. (Green’s)

We prove (test or approve) the will of God by believing and acting on the gospel of the kingdom. The kingdom comes with power, not by the words of men. It is righteousness, peace, and joy in the Holy Spirit.

The renewed mind is one that understands what the kingdom is like.

It is only observable through the actions of its members. We prove the will of God when we see this, and then go and demonstrate it by healing the sick, proclaiming the gospel of the kingdom, and loving one another.

Having faith toward God and in Jesus is the faith of God – the God kind of faith.

By it we are made righteous and saved, laying hold of what God provided by His grace. By it we exercise all authority over sickness, bondage of evil, and even death. It is not the world’s kind of faith. It is the God kind, eternal and true. People put their faith in many things and many gods, but that faith is futile. Only the faith of God operates in the kingdom.

In other words, we can’t have faith in just anything. The world, and yes sadly even Christianity, has programs, and motivational speakers, and spiritual leaders that are blind. You can motivate yourself and believe you are great, attracting money or love, or that you will please God. It may even seem to work for a while. But it is not the kingdom, which is eternal and leads to life.

The end of all that other stuff is death, because it is faith in what you can do. Doing doesn’t make it so. Doing doesn’t make it real. Just because you believe a thing doesn’t make it so.

It must be so – before you believe it!

What is so is that Jesus has rescued us from the need to please or perform, and has given the kingdom into our hands. Have faith in this.
