Q. You have written about having enough faith to believe we can be healed, and my emphasis is on the word, “enough.” It mildly disturbed me when I read that because the question that came up in my mind was, “Did I have enough faith to be saved, and if so why isn’t that same faith sufficient to believe I could perform miracles?”
A. When you asked for salvation you were given the faith to believe you had received it (Ephesians 2:8-9). It was a gift from God. 2 cor. 1:21-22 says at that time God set His seal of ownership on you and put His Spirit in your heart as a deposit guaranteeing what is to come. So you don’t ever have to worry about your salvation.
After we’re saved we’re supposed to yield our life to the Lord (Romans 12:1-2) and trust fully upon Him for everything, learning to live by faith (2 Cor. 5:7). The purpose of this is to help the faith we were given grow and become stronger. It’s similar to making the muscles we were given stronger through regular exercise. Sadly many people don’t do this and while their salvation is never at risk, they don’t develop the kind of “mountain moving faith” the Lord desires for us (Matt. 21:21-22).
Remember, the Lord’s promises are constant. It’s our faith that wavers.
