Here is such a help quotation from Paul David Tripp on the challenge of living at the intersection between faith and the reality surrounding you:
When you’re in the intersection between the promises of God and the details of your situation, what you do with your mind is very important. In this intersection, God will never ask you to deny reality. Abraham did not deny reality. Romans 4 says that he “considered the deadness of Sarah’s womb.” Faith doesn’t deny reality. No, it is a God-focused way of considering reality..
