Why do we not evangelize? Mark Dever provides one explanation: it has the potential for immediate discomfort. Someone might get mad at us, they might reject our message, etc.
We typically want to process our experiences immediately, and if they are unpleasant, we are inclined to change course in order to some way avoid the discomfort of the difficult comment or the pain that comes to us by a long obedience.
Mark Dever, The Gospel and Personal Evangelism (p. 98)
And yet we are called to a long obedience, as unpleasant as it may be. We are called to evangelize, and other duties that produce immediate unpleasantness (discipleship, exhortation, rebuke…). And we are called to rejoice in the unpleasantness, even to the point of suffering and persecution.
1 Peter 3:13-1713 Now who is there to harm you if you are zealous for what is good? 14 But even if you should suffer for righteousness’ sake, you will be blessed. Have no fear of them, nor be troubled, 15 but in your hearts honor Christ the Lord as holy, always being prepared to make a defense to anyone who asks you for a reason for the hope that is in you; yet do it with gentleness and respect, 16 having a good conscience, so that, when you are slandered, those who revile your good behavior in Christ may be put to shame. 17 For it is better to suffer for doing good, if that should be God’s will, than for doing evil.
