Why is Abel considered righteous in the Bible?

Abel's righteousness stems not from his actions alone, but from the faith behind his offering. In Genesis 4, God had respect for Abel's sacrifice because it was made in faith, demonstrating an understanding of God's holiness and his own need for redemption. This concept is critical in the Reformed tradition, which teaches that it is through faith that one is counted as righteous, as highlighted in Hebrews 11:4 where Abel’s faith is commended. This righteousness is imputed to believers today through faith in Christ, the ultimate perfect sacrifice.
