Today I replied to an email I received from a friend from my past life, before I was saved. It was a forward containing pornographic images. I have witnessed to him multiple times, and he is well aware that I am a Christian. What do you say to someone whom you have shared the gospel with and they reply, "Been there , done that?" Well, in my email I told my friend about catching a cold. I informed him that if we wake up one morning with a sore throat and cough, this is an indication that we have a virus. Likewise, when we entertain and enjoy images that are an offense to God in a habitual manner, this may be a sign that we are spiritually ill. I informed him that our heart is deceitfully wicked and that we must be born again or we will not see the Kingdom. I ended with a plea for him to examine his heart, turn from his sins, and place his trust in Christ.
