Make sure the young people growing up in your home, or your church, are involved in the work of the Lord. Are they engaged or disengaged? Do they participate or observe? Do they know how the Lord added their family to the church? Do they testify in church? Engage them in conversation. Ask them about their salvation, their understanding of the mission of the body of Christ, and the future. Above all, make sure they know they are a part of the church. It is easier to walk away when someone feels no attachment. They will not be the church of tomorrow if they are not an active part of the church today.
