Grief. Joy. Two very strong emotions on different ends of the spectrum. But both can and should be experienced by Christians when we look at our fellow brethren.
Grieved when we see them go after the things of the world.
Joy when we see them follow after Jesus.
Are you that concerned with other Christians that the stance they are taking spurs you to experience such emotion?
Christians, we are in this together. Our job is to spread the gospel of Jesus Christ. The stance fellow Christians take should encourage us either to exhort one another or to pray for the weakened brethren. Never should we just be nonchalant and unaffected by how our Jesus is being represented.
