They are afraid that there are strings attached, that if they reach out to take the best that God has to offer, there might be a chain on it or that God was only fooling. Think it over a while. There is another aspect of faith, and that is that we trust Him to take care of us, His children. These words are especially common in Paul's last 7 epistles. Charity is used in a couple of occasions instead of love, but back in 1611, charity did mean love.
Faith is belief in action.
And it is faith toward God. It comes by hearing the Word of God. Faith cannot be controlled by the will. It is the accepting of facts presented. Nothing hinders faith like self-will.
