Well I hear what you are saying, but it doesn’t change that people need the Gospel, presented in love, and THEN the Holy Spirit will work on them.
Your approach is likely to drive people away.
"Your approach is likely to drive people away." Wrong! That is the American myth! No wonder the American style of evangelism is a washout. And American churches are dying. I think you should read Lester Roloff's great sermon on Dr Law and Dr Grace. it is well-known in serious evangelical circles. That was in the good old days when America was a strong country - strong spiritually.
Paul first focused on sin in Romans. Read Romans chapter 1.
In chapter 2 of Romans, he indicted both Jews and Gentiles. (And the moralists from both sides.)
Only in chapter 3, does he bring in Grace.
God's love is not a wishy-washy love. it is tough love! Holy love! Fiery love! The fire will burn out sin.
P.S. I believe 100% in the Gospel of Grace. I believe in the Inseparable Love of God. But I will not accept this silly 'kid-glove' approach to stubborn sinners. Let them know they are sinning. The Holy Spirit will convict them.
