I believe we should always give the gospel and invite people to respond. When I was in the pastorate, I tried to make the gospel clear in all my sermons and to give people a chance to respond. Sometimes that meant standing up, sometimes it meant raising hands, sometimes it meant coming forward for prayer. I varied the methods but always wanted people to have a chance to “close the deal” with the Lord. I say that understanding that the Holy Spirit must give the true invitation because without the Spirit, no one can come to Christ.
