How can I avoid falling into self-righteousness?

To avoid self-righteousness, as discussed in the sermon, one must constantly guard their heart and mouth while placing full faith in Christ's perfect righteousness. David's plea in Psalm 141:4 shows the need to turn away from self-reliance and false gospels that promote legalism. The Gospel teaches that our righteousness comes solely from Christ, and our role is to rest in His finished work. This understanding combats the natural tendency to trust one’s own morality or performance. Paul affirms this in Philippians 3:9, where he expresses his desire to be found in Christ, not having a righteousness of his own, but one that comes through faith in Jesus.
