Why is Christ alone the focus of salvation?

The focus on Christ alone for salvation is deeply rooted in the sovereign grace theology that underscores the entirety of Scripture. During the transfiguration, Christ conversed with Moses and Elijah, who symbolize the Law and the Prophets, respectively. The revelation that the Law was never intended to provide salvation, but rather to point to the coming Savior, illustrates why Christ stands alone in this redemptive role. The voice of God the Father commands, 'Hear Him,' emphasizing that all scripture culminates in Christ's work. He alone met the requirements of the Law, suffered for sin, and secured redemption, affirming that no other name under heaven can save. Thus, salvation rests solely on His finished work, encapsulating the essence of grace, which is central to Reformed theology.
