The church of Jesus Christ, his Body, has an intercessory role. We have a responsibility to pray for all people, stand on their behalf before God which means we must be able to identify with them. We cannot represent or intercede for persons we curse and already condemn. True intercession is a position of humility and God exalts those who humble themselves. The apostle Paul admonished us to pray for all people, not some. Praying for other is beneficial for us. We are able to live in and enjoy the peace of God which we would not have if we are busy hating and being bitter. Bitter people are not peaceful people, they are not happy people. Do you want to enjoy your life? Then make it your culture to pray for all people.
