This sermon explores the foundational question of why a person is called a Christian, grounding the answer in three distinct marks of genuine faith found in 1 John. The first mark is theological discernment, where believers recognize the truth of Jesus Christ as the Anointed One and reject the spirit of Antichrist that denies His deity and humanity. The second mark is spiritual consecration, defined by the internal anointing of the Holy Spirit, which seals believers and empowers them to serve as prophets, priests, and kings. The third mark is unwavering perseverance, illustrated by the contrast between those who depart and those who abide in the truth they heard from the beginning. The message urges the congregation to move beyond nominal identification with Christ to a deep, enduring relationship characterized by knowing the truth, sharing in the Spirit’s anointing, and remaining steadfast in faith until the end.
