Sermon, 18th Sunday after Trinity, 2026

The prayer appointed for the Eighteenth Sunday after Trinity asks God for grace to withstand the temptations of the world, the flesh, and the devil. Ephesians 2 identifies these three sources of spiritual opposition: a world hostile to Christ, the sinful nature that remains even after regeneration, and the demonic powers seeking to lead believers astray. These forces frequently work together, exploiting human weakness and challenging our obedience to God. Their influence also extends beyond temptations to sinful conduct, threatening our understanding of the faith and our confidence in God’s Word.

The grace needed to withstand these attacks calls for active participation in the spiritual life. Like a farmer who diligently tends his fields while depending upon God for growth, Christians must cultivate their faith through prayer, study, and obedience. In the Gospel, the Pharisees attempt to discredit Jesus, only to have their spiritual blindness exposed when he challenges their understanding of Psalm 110 and the Messiah’s divine identity. Their failure demonstrates the danger of religious knowledge without spiritual understanding. Through disciplined effort and dependence upon God’s grace, believers are called to grow in wisdom and remain steadfast in Christ.
