Christian apologetics is the branch of theology that is concerned with defending and explaining the Christian faith. It involves using reason, evidence, and logical arguments to provide a defense of the truth and reliability of the Christian faith, as well as to address objections and questions that may be raised by non-believers. Preevangelism, also known as pre-evangelism or pre-evangelization, is the process of preparing people to receive the gospel message. It involves building relationships and creating an environment that is conducive to hearing and responding to the good news of Jesus. Christian evangelism is the act of sharing the good news of Jesus Christ with others in an effort to lead them to faith in Jesus. It involves telling others about the love of God, the death and resurrection of Jesus, and the offer of salvation that is available to all who believe in him.
