Why does salvation bring glory to Christ alone?

In the gospel, Christ receives all the glory because the entirety of salvation is His achievement. As stated in Galatians 6:14, Paul declares, 'God forbid that I should glory, save in the cross of our Lord Jesus Christ.' The reality is that when we try to mix our efforts with grace, we undermine the very foundation of the gospel, which is that Christ's sacrifice is sufficient for our salvation. Believers must recognize that any hope of self-salvation is not only futile but also an affront to God's grace.
