One of my favorite Bible teachers says that, “Faith is like a blank check.” The blank check of faith is there for you fill in your need or desire and use it. I respect that and I respect him, but I would rather think of faith being more like a cashier’s check than a blank regular check.
A cashier’s check is written for a specific amount and for a specific purpose. It is a one-time authorized payment for a one-time need. If faith were a blank check to fill in whatever we wanted why would we then have to seek God and coordinate with His will. Once we hear and get the OK of faith, we can’t go and use it for something else. We can only use the faith for what was approved and intended.
Faith is issue specific and time specific. Faith is God’s specific promise coming alive in our heart for a specific desire. Faith, the Bible says, comes by hearing, so we cannot hear ‘healing’ and then go out and expect to receive a financial blessing. As seeds are specific, so the promises of God are specific, and the resulting faith is specific – as specific as a cashier’s check.
