What does it mean that God made the difference in salvation?

In 1 Corinthians 4:7, Apostle Paul questions who distinguishes one believer from another, emphasizing that the distinction comes solely from God. Theologically, this difference is not rooted in individual merit but is a reflection of God's electing love and grace. This doctrine of salvation asserts that it is God who initiates, sustains, and completes the work of salvation in His elect. It is only by His grace that we have faith and repentance. By recognizing this truth, we are called to humility, understanding that our faith is a gift from God rather than a product of our own efforts or decisions.
