In Hebrews 11:1, faith is literally a substance. It’s the foundation for what you’re believing for.
Think of it this way: your faith is the clay the Father uses to mold and shape, what you are believing for. He has given everyone a measure of faith, and He will stretch that faith until it grows to a substance He can work with.
Radical faith isn’t given, it’s cultivated, until it can be used.
