Christian courage is the willingness to say and do the right thing regardless of the earthly cost, because God promises to help you and save you on account of Christ. An act takes courage if it will likely be painful. The pain may be physical, Or the pain may be mental as in confrontation and controversy.
Courage is indispensable for both spreading and preserving the truth of Christ. Jesus promised that spreading the gospel would meet resistance: “Then they will deliver you to tribulation, and will kill you, and you will be hated by all nations because of My name” (Matthew 24:9). And Paul warned that, even in the church, faithfulness to the truth would be embattled: “I know that after my departure savage wolves will come in among you, not sparing the flock; and from among your own selves men will arise, speaking perverse things, to draw away the disciples after them” (Acts 20:29-30; see also 2 Timothy 4:3-4).

Therefore, true evangelism and true teaching will take courage.
