How do we know salvation cannot be bought?

The idea that salvation cannot be bought is firmly rooted in Scripture. Gehazi's attempt to accept gifts from Naaman starkly contrasts with Elisha's refusal to take anything, highlighting the principle that God's grace is freely given and cannot be earned. In verse 20, Gehazi's statement reflects a misunderstanding of grace that many share—the belief that something must be given in exchange for spiritual benefits. However, the Gospel teaches that 'In my hands, no price I bring, simply to Thy cross I cling.' This aligns with Ephesians 2:8-9, which states that we are saved by grace through faith, and not by works, so that no one can boast. The notion that spiritual blessings require payment undermines the very essence of the Gospel; salvation is solely reliant on Christ's finished work on the cross.
