What does it mean that Abraham's faith was counted for righteousness?

When Scripture states that Abraham's faith was counted for righteousness, it reveals a profound theological truth: God ‘reckons’ righteousness to those who genuinely believe in Him. This willful acknowledgment of faith is not a mere accounting trick but an affirmation of the righteousness that comes from Christ, as understood through the imputation of Christ's righteousness to believers. Romans 4:3 illustrates this by emphasizing that faith counts as righteousness, highlighting that our justification is rooted not in personal merit but in our trust and reliance on God’s promises. This doctrine serves as a clarion call to believers, ensuring them that their standing before God is securely anchored in faith.
