2 weeks ago, the teacher asked me why I always talk about salvation every week. Well, over the last 2 weeks, we have found out. This class isn't ready for anything other than a salvation message.
We need to continue to proclaim that message, knowing that the Holy Spirit will bring conviction of sin, and that it is He who will plant belief in new hearts.
That is why I told xzins that if I was ever invited to preach in his church I would tell his congregation that they need to repent of their sin and believe on the Lord Jesus Christ.
