The ministry of Jesus Christ is an outreach ministry. Each of the four Gospels ends with a commission from Christ to His church to carry the Gospel message to the ends of the earth (Matt. 28:18-20; Mark 16:15; Luke 24:46-49; John 20:21-23; and see Acts 1:8).
The links will show you various ways you can minister to those within and outside of the church. How will you know one of these ministries is where the Holy Spirit wants to place you? You will know because it is something you will be drawn to do. Moving with the Spirit always increases your comfort level. Going in any other direction, or just staying still, always make you uncomfortable.
