For the Spirit God gave us does not make us timid, but gives us power, love and self-discipline.-2 Timothy 1:7
Paul is reminding Timothy here that as a follower of Christ, who has been indwelt with the Holy Spirit, that he has nothing to fear and that he has no reason to be timid. What then does the Holy Spirit give us? He gives us power to go out and boldly fulfill the mission that God has given us. He fills us with a love for God and a love for others. And he gives the guidance we need to help us not stray from the mission that God has called us to do.
Why as followers of Jesus do we have nothing to fear? The worst the world can ever do to you is kill your body. As a follower of Jesus the moment you die your spirit goes directly to be in the presence of Jesus. As a follower of Jesus death is not something we should fear, because it is only the end of our earthly existence but it is the beginning of our heavenly existence. That is why Paul reminds Timothy and us that God does give a spirit of fear or timidity. Don’t live your life in fear of what the world can do to you, but live your life boldly for Christ.
