Many of us never evangelise because of fear. And some never see the full potential and power in the blood because of fear. Fear that it will not work. Fear is like a rope which Satan uses to tie us down. Fear causes us to focus on what Satan is doing or can do.
Fear is the opposite of faith.
Faith causes God's power to work on our behalf. Fear stops it. We should resist fear just like Moses did. The halfhearted approach. Let your little ones also go with you.
