Quote by John MacArthur

“Although every true believer knows it is a serious sin to be ashamed of his Savior and Lord, he also knows the difficulty of avoiding that sin. When we have opportunity to speak for Christ, we often do not. We know the gospel is unattractive, intimidating, and repulsive to the natural, unsaved person and to the ungodly spiritual system that now dominates the world. The gospel exposes man’s sin, wickedness, depravity, and lostness, and it declares pride to be despicable and works righteousness to be worthless in God’s sight. To the sinful heart of unbelievers, the gospel does not appear to be good news but bad (cf. my comments in chapter 1), and when they first hear it they often react with disdain against the one presenting it or throw out arguments and theories against it. For that reason, fear of men and of not being able to handle their arguments is doubtlessly the single greatest snare in witnessing. It is said that if a circle of white chalk is traced on the floor around a goose that it will not leave the circle for fear of crossing the white mark. In a similar way, the chalk marks of criticism, ridicule, tradition, and rejection prevent many believers from leaving the security of Christian fellowship to witness to the unsaved.”
