Learn the Word of God!
If you need food and I don’t have any food there is nothing I can do to help you eat. The same is true if we desire for God to use our mouths to bring His sheep to faith. If we are not learning the Scripture, we are not being prepared to have proper evangelism in our lives. Outlines, acrostics, pneumonic devices, “roads”, examples, apologetics, evidence etc. cannot bring ONE person to faith. Only Scripture can give you the tools to give others the truth!
“Half truth is no Truth, like being half dead.”
