The Gospel changes lives and something that powerful must be guarded.In 1 Timothy, Paul writes a letter to Timothy encouraging him to be bold in his faith and to stand up against the teachers who are preaching false doctrine. Timothy was timid and needed to be reminded to be bold. These teachers had strayed from their faith and what was right and were leading others astray. Unlike their teaching, correct teaching should produce a good conscious, a pure heart, and a sincere faith.Paul taught the power of the Gospel by sharing his testimony and how the Lord had radically changed his life. When was the last time you stood by the Gospel and shared your testimony?Any effective way to share the power of the Gospel with others is to share what God has done in your life.In today's world, it's going to take courage and boldness to defend your faith. But the Gospel is powerful and worth fighting for.
