While both religions emphasize faith, they define it in radically different ways. Christianity teaches faith as trust in God’s redemptive plan, culminating in Christ, while Islam sees faith as submission to divine law, with no guarantee of salvation.

The notion of atonement in Christianity differs significantly from that of Islam. The Qur’an explicitly rejects the idea that one person can take on the sins of another:

Hebrews 7 presents Jesus Christ as the eternal High Priest, whose work of intercession is perfect, complete, and irrevocable. In contrast, Islamic theology offers a model of intercession that is conditional, uncertain, and ultimately dependent on the will of Allah.

In Christianity, the book of Hebrews 6:4-6 presents a severe spiritual warning about falling away from Christ—without prescribing any earthly punishment. In contrast, Islam treats apostasy (riddah) as both a theological and legal offense ...

Hebrews 5:1-11 paints a picture of a Savior who doesn’t just show us the way to God but becomes the way. Unlike earthly priests, who were weak and temporary, Jesus is the eternal mediator who fully satisfies God’s justice while extending mercy.

Christianity proclaims a God who comes near, suffers with us, and redeems us through His own sacrifice. Islam, however, presents a God who remains distant in terms of personal relationship, though the Qur’an speaks of His closeness in sovereignty and knowledge.

The first chapter of Hebrews is one of the most powerful declarations of who Jesus truly is. It leaves no room for the Islamic belief that Jesus was just another prophet or a created being.

[Our union with Christ is] not merely a doctrine to be acknowledged, but a reality to be lived. It is the very heartbeat of salvation, the foundation of the Christian life, and the key to understanding both our identity and our transformation.
