Matt 14:31:
And immediately Jesus stretched forth [his] hand, and caught him, and said unto him, O thou of little faith, wherefore didst thou doubt?
1 Pet.2
7 Unto you therefore which believe [he is] precious: but unto them which be disobedient, the stone which the builders disallowed, the same is made the head of the corner,
8 And a stone of stumbling, and a rock of offence, [even to them] which stumble at the word, being disobedient: whereunto also they were appointed.

You can not force your given faith in Jesus Christ or our faith given in doing miracles or even healing onto other fellow believers and not to unbelievers of course.
Faith is a gift and it comes from hearing the Word of God. (Or study/meditating.) Some say that we have unbelief because we don’t wake up dead. Or cast out demons. Well Jesus mention that some time demons don’t leave because of little faith.
But mainly, and as a very clear Biblical fact, unbelief has to do with disobedience. Ref. 1. Peter 2:7-8. And of course many other places we find the same. The Sin is after all disobedience. Ref. John 14-15-16.
If we do things without faith in the spiritual we sin. So to try to push onto others your faith with the intention that they should act on your faith will be to tempt people into sinning.
We can talk about miracles as much as we want. But button line will be that if you want to do the greatest ting you harvest people for eternal life. Remember what kind of party there is in Heaven when only one repents! The miracle to be born again is so great that Jesus say we will never in this life be able to explain it.
Have a blessed harvest from now and until Jesus come back. GO OUT!
