Why is the distinction between believers and unbelievers important for Christians?

The distinction between believers and unbelievers is crucial for Christians as it clarifies the nature of salvation and the sovereignty of God in the redemptive process. Throughout Scripture, God is depicted as the one who selects His people, and this selection is not based on any merit or action on our part. For instance, John 6:44 states, 'No man can come to me, except the Father which hath sent me draw him,' emphasizing that true faith is a gift from God. Recognizing this distinction provides believers with assurance of their salvation, as it underscores that it is God's grace that leads us to faith. This understanding encourages Christians to rest in God's sovereign will, knowing that their standing before Him is not contingent upon personal effort but is secured by Christ's obedient sacrifice.
