Walking by faith is like walking blind but trusting in the One who guides you through His inner voice. You operate in your 5 senses, spiritually being sensitive to the senses. When you feel heat it is a sign of His presence. You flow in the Spirit. You operate in the Spirit rather than the flesh. In this way, you are protected from doubt as you move forward by faith. You take risks that naturally you would not. You stop worrying and procrastinating. You are moved by the Spirit to do. You leave the results to Him. You are led in the moment and not in any planned way. This is to move freely and the people on the receiving end will receive in the spirit too. What is done in the spirit will be received in the spirit. What is done in the flesh will be received in the flesh. You have been called apart to operate in the spirit. In the spirit world, there is an unseen reality. God operates in the Spirit because He is Spirit. Man operates in the flesh and the spirit. This is why Jesus came in the flesh so that He could show man how to operate in the spirit while living in the flesh. Many did not understand the things of the spirit for they were blind. So also in this world, many will not understand and die in their ignorance. You are called to proclaim the truth in the Spirit and leave the rest to God
