Be ready to spread the word whether or not the time is right. Point out errors, warn people, and encourage them. Be very patient when you teach. .... But you must keep a clear head in everything. Endure suffering. Do the work of a missionary. Devote yourself completely to your work. (2 Timothy 4:2, 5 GW)
Paul encouraged Timothy to preach he gospel to spread the Christian Faith throughout the world. We believe in Christ today because of people like Paul and Timothy. It may be inconvenient to take a stand for Christ or to tell others about his love, but preaching the word of God is our most important responsibility. This can be as simple as living a life that truly represents Jesus Christ. We should always be prepared in season and out of season to serve God in any situation, being sensitive to our opportunities. Keep your head in all situations because temptation is always at the door. Live a life that bears testimony to God's glory. Be courageous!
