Paul speaks of being in the anguish of childbirth because of the situation in Galatia. He took in the pain they were in danger of inflicting on themselves. He cared deeply for their spiritual wellbeing. He beautifully reflected God's love to them.
We may not be able to carry the pain of the world, but we can certainly open our hearts to those who are hurting, struggling, sinning, and suffering - if only to a point. To do so reflects Christ's love for all people. Bring them to Jesus who carries our sins, griefs, and pains, and makes it possible for us to open our hearts to others in their times of struggles and pain.
