What makes a difference between believers and non-believers?
Answered in 1 source
The principal difference is God's sovereign grace, which distinguishes believers by the work of Christ applied to their lives.
The distinction between believers and non-believers rests upon the sovereign grace of God. In Exodus 11:7, it states that the Lord put a difference between the Egyptians and Israel. This principle continues into the New Testament, where Ephesians 2 declares that believers were once dead in sin but have been made alive through Christ. The difference lies in God's initiating grace; He chooses, calls, and transforms those whom He saves. This grace is not given based on any merit or decision from the individual but is solely dependent on God's merciful will. Therefore, believers rejoice not in their own righteousness but in what God has done through Christ.
