To believe without a doubt. To believe with constraints on God. We as humans concoct a thought that we must do before something happens. We do nothing but limit God by these thoughts. There is no limits to what God can do for He can do anything. We look at circumstances and think that, "if someone would just go visit them". We often tie the miracle to something we conceived. Faith comes by hearing and hearing by the Word of God. The Word of God is critical in our Christian growth. The things that were done while performing the miracles was not necessary in order for the miracle to take place. Only His word was needed along with the faith of the person for the miracles to be fulfilled. Faith isn't limited by earthly limitations. Humans do not have to be involved for miracles to take place.
