Jesus Christ, the Son of God, left all the glory of the heaven behind and came to the earth to save human beings. He didn't eat well nor did He sleep well, however because of the souls, He preached the gospel of salvation in earnest. In the end He was crucified on the cross. In the same manner, we have to put others before ourselves and take care of them to accomplish His true love in our hearts. When we seek the good of others, God will give us even more blessing.
"In everything I showed you that by working hard in this manner you must help the weak and remember the words of the Lord Jesus, that He Himself said, 'It is more blessed to give than to receive.'" (Acts 20:35)
