Witnessing for Christ is one of the tools that The Lord uses to save sinners. Those who have been saved need to be actively engaging their lost family members, friends, and work associates in spiritual conversations about Christ. We need to plant and water as much gospel seed in their lives as we can. And we need to trust the Holy Spirit to effectual call them to Christ. One simple thing that we can do in our witnessing for Christ, is to invite our friends to church. This sermon is about inviting friends to church on Friend Day.
