How do we know that Christ's selflessness is a model for us?

In Romans 15:3, Paul quotes Psalm 69 to illustrate how Christ lived not for Himself but for others, taking the burdens and reproaches upon Himself. This profound act of self-denial and love sets the benchmark for our own behavior. We are called to follow His example by prioritizing the needs of our neighbors, practicing humility and selflessness in our daily interactions. This Christ-centered approach fosters a community of believers that reflects His love and grace, ultimately bringing glory to God.
