It can feel useless. But faith is a solider (more solid) base than what might you think. Now faith is the SUBSTANCE of things hoped for, the evidence of things not seen — Heb. 11:1 KJV (caps mine).
The KJV’s word “substance” is hypostasis, which is translated elsewhere “confidence.” It’s a foundation, a basis. Words uttered with faith are not wispy sounds that disappear into thin air. Their sound waves may die, but their essence moves angels into action. God spoke, and the world was created. He made us in His image — with the ability to speak into existence things that are not.
With the strident monotony of blah-blah-blah bombarding us continually from the television, the radio, the internet, we can forget that words CAN have meaning and impact. Don’t compare prayer to the media’s drivel.
Prayer activates — like the propulsion of a rocket launch. Prayer unlocks — like a password. Prayer smashes down strongholds, builds up Cities of God. It is quicker than a Google search, more effective than the U.S. military taking on North Korea. It moves unseen behind enemy lines and converts to Christianity its sworn enemies (like Paul).
The Bible says faith can move mountains. We have so many more metaphors today.
