People need to hear the kingdom of God preached, but we must be diligent when telling people about the gospel. Sometimes it takes a little hidden preaching–a little ninjitsu Christianity–in order to dissuade a person from doing evil so that one day he or she can fully receive the message of Christ.
If you have a friend living in lust, he may not respond well in learning that God is going to kill him for his unrepentance. Instead, plant a seed in him of pure living by saying things like “Man, I am so glad I am no longer having sex with multiple partners. I used to do that and that life just used to wear me thin, but, wow, I will never go back to it because of how good it feels to be free.”
The goal is to prep him for the day that you or a different saint can finish the Lord’s work by leading him into the arms of Christ. You should pray that he asks you how you were able to break the bondage of lust, because then you will be able to share with him the wonderful power of your Savior, Jesus Christ.
“But you are a chosen people, a royal priesthood, a holy nation, a people belonging to God, that you may declare the praises of him who called you out of darkness into his wonderful light” (1 Peter 2:9).
There have been many instances where the Lord has used less subtle words to get his message across, and there are times when a less subtle approach works. All good parent’s discipline their children, and sometimes, enough is enough.
Dear children, do not let anyone lead you astray. He who does what is right is righteous, just as he is righteous. He who does what is sinful is of the devil, because the devil has been sinning from the beginning. The reason the Son of God appeared was to destroy the devil’s work. No one who is born of God will continue to sin, because God’s seed remains in him; he cannot go on sinning, because he has been born of God. This is how we know who the children of God are and who the children of the devil are: Anyone who does not do what is right is not a child of God; nor is anyone who does not love his brother. (1 John 3:7-10)
