Some refer to Romans 10:1 when asked for a Bible reference concerning prayer for unbelievers, “Brothers, my heart’s desire and prayer to God for them is that they may be saved”.
I’d like to suggest another one, John 17:20, where Jesus prays not only for those who are alive at that time and do not yet believe but also for those who are not yet born but will believe – “I do not ask for these only, but also for those who will believe in me through their word”. Jesus prayed beforehand for those who were saved on Pentecost and for every believer after that to be joined to the body, to be one even as Jesus and the Father are One (v. 21). We need to pray for God to give us and make us workers for the harvest (Matthew 9:37-38).
Do you pray for your community? For your family and friends? Pray that God would raise up workers, that God would allow the harvest pour forth from His hands!
