How about praying for anyone who is under conviction of sin? How about praying for the Holy Spirit to overcome any spiritual blindness in anyone who in the congregation or meeting who may be unsaved (II Corinthians 4:4)? How about asking God to reveal Christ through the gospel to anyone who has not received Christ as Lord and Savior (II Corinthians 4:6)? How about praying for anyone who does put his or her faith in Christ for the first time to become rooted and grounded in Christ (Colossians 2:6-7) and become a faithful disciple of Jesus for the rest of his or her life (Matthew 28:18-20)?
It’s not a good time to sit around waiting for the end of the service or meeting, and perhaps thinking about lunch, or what you will be doing the next day. Rather spend the time participating in the spiritual warfare for the souls around you. And if you’re a pastor or teacher giving an invitation, it’s a good idea to request this kind of prayer from the long time believers who may be in attendance when you’re explaining the gospel and perhaps giving an invitation. So often we forget that the very act of sharing the gospel and giving someone else directions on how to enter the kingdom of God through repentance and faith in Christ is a time of spiritual warfare that needs to be bathed in united prayer.
