You are so very correct in saying that evangelism is not criticism. A lot of times you see people criticising others in the name of evangelism. While we should not endorse sinful lifestyles, our focus is to share the message of Christ: that He is the Son of God who came to this world to die for our sins and was raised again to life by the Father and is now King of Kings and Lord of lords. Whosoever believes in Him will not perish but have everlasting life. Criticising peoples’ looks, dressing and appearance in the name of evangelism is counter-productive and doesn’t show the love of God. Our job is not to judge the sinner but to love them and share the gospel with them. Also, I love the fact that you said evangelism is not by force because these days, some people get angry when the people they are trying to preach to refuse to accept Christ. It sometimes becomes a shouting battle. This is totally uncalled for. While we are called to preach, we do not have the power to convict anyone, that is the job of the Holy Spirit, so if a person refuses to accept Christ, the best we can do is pray for them and keep following them up. With time, the Holy Spirit will do what only Him can do.
