That grace, having spread through the many, may cause thanksgiving to abound to the glory of God.
2 Corinthians 4:15
Many people think the main reason God saves people is so that He can keep them out of hell, or so that they can experience His love or lead happy lives. But all those reasons are secondary.
God saves people because it is an affront to His holy name that someone should live in rebellion against Him. That people experience salvation is not the main issue with God—it is His glory that is at stake.
The apostle Paul said of Jesus, “God also has highly exalted Him and given Him the name which is above every name, that at the name of Jesus every knee should bow, of those in heaven, and of those on earth, and of those under the earth, and that every tongue should confess that Jesus Christ is Lord, to the glory of God the Father” (Phil. 2:9–11). Salvation is for God’s glory.
God is glorified when people believe His gospel, love His Son, and accept His diagnosis of their greatest need, which is forgiveness of sin. You certainly benefit from God’s provision of salvation, but you exist for the glory of God.
