Like the law of gravity, there are certain predictable things about the law of serving others.
Those who serve do not dwell on themselves. They are doing things that are not convenient or self-protective. They are always giving of their own resources, so they exempt themselves from the fear of being without.
Serving to Body of Christ means being around and loving the unlovely. It is not always possible to know the real from the fake, and there are needs all around.
Soldier of The Cross, look at Him. He gave Himself as a Ransom for Many. Because of Love. He did not protect Himself
Loving and serving others does not make milky, push-over Christians. Serving those in need brings awareness of the difference between users and those who genuinely need help.
There is no lack of opportunity.
Prepare in prayer. Then go somewhere and do something.
