God sent his Son into the world not to judge the world, but to save the world through him.
John 3:17 NLT. 

If God's plan was not to condemn but to save people, who are you to judge people or condemn people? Say No and avoid anyone who preaches the Gospel to you by condemning you because of sin because, it's possible they may not be sent by God.

God sent Jesus not to judge but to save, therefore anyone representing Him will do the same thing for the same purpose. Remember you are loved by God even if you are not a Christian yet, but if you already are a believer please go all out today basking in God's unconditional love shared abroad in our hearts in Christ. Forget everybody!!!
