In Solus Christus – Christ Alone, Aidan Sims reminds us that our salvation rests entirely on the finished work of Jesus, not on anything we can add. Like a rider who must keep their eyes fixed on where they want to go, the Church must keep its gaze on Christ alone, lest we drift toward “Jesus and…”—Jesus and good behavior, and religious observance, and social causes. From Genesis to Revelation, Scripture reveals that God’s plan of redemption is fulfilled in Jesus—the promised Seed, the true Tabernacle, the eternal King. Fully God and fully man, Christ lived in perfect obedience, bore our sin, and rose to reconcile us to the Father. Through the Spirit, we are united to him so that his story becomes ours—his death our death, his resurrection our life. Salvation is wholly God’s work, accomplished by the Son and applied by the Spirit. When we look at ourselves, we see only our unworthiness; but when we look at Christ, we see the unshakable assurance that we cannot be lost.
