Remember to preach the word of God without compramising the Gospel. Consider that you may be in danger in some place because some people are offended by the truth. But you don't have to be afraid, if you have faith in God, he will protect you always. Remember Daniel who have faith in God was not eaten by the wild lions. Consider that if you preach in public, more sinners will surround you but don't be afraid, remember Jesus was criticized by being around the sinners and remember Jesus' apostles committed sin.
