The command is simple, yet we often fail to do it. Why?
There are 3 people groups that are increasingly difficult to share with, each with its own set of challenges.
Strangers or casual friends are a challenge, because you need to have a serious conversation completely out of the blue. It’s good to get into the habit of sharing the gospel with this group to give you experience and confidence for when you move to the more difficult groups. Begin each day in prayer, asking God to give you an opportunity to share the gospel. You will be surprised at how faithful He will be to bring those opportunities.
The second group would be your close friends. By proclaiming Christ to close friends, you risk losing the friendship. You will also permanently alter the friendship. When you tell a dear friend that they have sinned against a holy God, your relationship to them will be forever changed. But if they are a true friend and you confront them with sincere concern for their soul, I think they will respond well. Our goal in sharing the gospel is not to make GOC larger, or add to a club. Our goal is that Christ would be exalted, that His saving work would be proclaimed, and that our dear friends would be saved. If we love our friends, how can we not share Christ with them?
The third group, family, is very difficult because they have inside knowledge of your entire life. They have seen your sinful tendencies. Who are you to tell them how to live when most of what they know about you is your sinful past? I suggest you use that to your advantage. Admit that your past was sinful, that you are ashamed of the disrespect you showed to your parents and ask for their forgiveness. Tell them that moving forward, as a Christian, you want to please God by honoring them.
The command is clear, but the challenge can be great. 2 Timothy 4:2 tells us to preach the word, and to be ready in season or out of season. Today, it almost always feels like we are out of season, but we must be prepared to preach the word, and the good news that Jesus Christ is the Savior.
