Some say seeing is believing. In John 20:29 Thomas gets an ear full for that closed mindedness. We also get another beatitude. Blessed are they that have not seen, and yet have believed. We have actually seen people who claim Christ say, “I’ll believe it when I see it.” That attitude has nothing to do with faith and everything to do with humanism. Faith in Christ has to stretch beyond the physical to the spiritual. However, it usually manifests itself physically. You usually see the results of faith, or the absence of faith.
Hearing and listening are also connected to believing. We often listen to things and superimpose our own thoughts onto what we hear in order to understand. That can be helpful except when it changes, or disregards the actual meaning. Some great orators are actually very skilled in the ability to speak in open and undefined concepts that give hearers freedom to impose their own thoughts on the oration. People can gather many different ideas from one speech, all of them of their own individual design.
Jesus never did that. He spoke very directly unless He knew His words would be intentionally misconstrued. Even then He stood silently before false accusation. When Jesus told the disciples He had to suffer death and be buried three days then return (Matt 12:39), they heard about Jonah not about Jesus.
We will serve our spiritual life and life in Christ far better if we point our thoughts toward Jesus with the things we hear, good or bad. Good to praise Him. Bad to seek forgiveness, protection or deliverance. Fix your eyes upon Jesus. Your faith will grow in His grace and mercy.
