Let's say that you want to do everything out of the joy that comes from knowing the Lord. Well, a lot of people aren't built like that emotionally. If they think that some sort of feeling is the basis for their action, they are going to feel justified sitting around, although they are going to feel bad that they have never taken one step of obedience because their heart is cold.
Mark DeverWe live in a time when people are increasingly skittish about evangelism - Christians and non-Christians alike. People are suspicious of evangelism, and misunderstand it, which contributes to our reluctance to share the gospel. When you add our fear of others' reactions as well as our natural laziness to the equation, it's not hard to see why we make such little progress in sharing our faith.
Mark DeverDo you want to know that your new life is real? Commit yourself to a local group of saved sinners. Try to love them. Donโt just do it for three weeks. Donโt just do it for six months. Do it for years. And I think youโll find out, and others will, too, whether or not you love God. The truth will show itself
