Selfishness, self-centeredness, and self-pity lie at the root of most mental and emotional issues, as well as all bitterness, anger, and wrath. The depth of our selfishness is revealed by our attitudes and priorities. When we prioritize ourselves—our problems, possessions, or pride over the needs of others, we show that we have no charity. Following Christ requires the denial of self, which is difficult, but essential. Christ's life on earth was marked by compassion and concern for others, and believers are called to "...let this mind be in you, which was also in Christ Jesus." True service to God is not in religious appearance or competition, but in genuine acts of love and care for others. This matter is the heart of the Gospel: Jesus gave Himself for us, and we are to do the same for others. The path to joy, soundness of mind, and eternal life is summed up in this simple truth: "Jesus first, others second, self last."
