I’ve heard and read the story of Cain and Abel several times, but I’ve never seen it explained so well! This is worth the read.
Abel’s different not because of what he offered but because of what he didn’t offer. Abel doesn’t believe God owes him anything. Abel’s faith isn’t in what he brings to God, but in what God has given to him. Abel’s offering is a better offering, it’s simply an offering brought in faith (Hebrews 11:4).
