Here is another post on the topic of evangelism. Here are four simple reasons that Christians need to share their faith.
1. Jesus is the only way to God. See John 14:5-6, Acts 4:12 & 1 Timothy 2:5-6. I believe this is true. As a result I need to make sure everyone comes to follow Jesus if I want them to be in heaven.
2. Jesus came down from God to bring man to God. Most people have figured out their own religion and it is usually the same. It goes like this; I need to do better and better and hopefully I will one day reach God. Then he will be happy with my efforts and let me into his heaven. Christianity is very different from what we might figure out on our own. God comes down to man because we will never be good enough to reach God on our own.
2. Christianity is based on a historical event. We believe that Jesus came and lived and died as a historical event. We would not know history without someone telling us what happened. We cannot figure out the past on our own. No one can, so we need to explain what Jesus did back then. See 1 Corinthians 15:1-8. The apostles did not just teach what they believed, they taught what they believe happened.
4. Without Jesus there is judgment. If Jesus is the only way to heaven then those who do not follow him are on a different path leading to a different place. I believe this place is a real place called hell. In Luke 16:19-31 Jesus tells about a rich man and Lazarus. In verses 27-28 the rich man is very concerned about this brothers. He does not want them to come to this place of torment. There is this simple truth, the people in hell want us to tell other people about Jesus so that they do not end up there.
I believe there are other reasons to share our faith, but these are four big motivations…at least for me. I hope they are for my class and maybe for you.
