God’s heart is for the lost. You are His ambassador/His spokesperson.
'I am not ashamed of the gospel of Christ for it is the power of God to salvation for everyone who believes...' '...How shall they believe in Him of whom they have not heard?’ Romans 1:16 / 10:14.
Remember you may not be an evangelist, but we are all called to witness. Jesus came to 'seek and save that which was lost '. We may be afraid, but remember, ‘He who is in you is greater than he who is in the world’ 1 John 4:4. "God is love” 1 John 4:8. / 4:18. ‘There is no fear in love, but perfect love casts out all fear'.
Jesus said, “I will never leave you or forsake you. The Lord is my helper I will not fear. What can man do to me?" Hebrews 13:5,6 and Matthew 28: 20 "I am with you always even to the end of the age."
