Blessing the older son is distinctly Middle Eastern having two basic ideas behind it. One, the Father would speak well of the older son, which meant he was worthy of his father’s respect. Two, the son would receive the blessing because he was worthy; his work, and character brought honor, protection, and prosperity to the rest of the family.
Paul in his letter to the Ephesian believers began with the profound thought that all believers are blessed, but how does a sinful wretch receive a blessing from God? The answer is found in two words, “in Christ.” Christ is the older son who is worthy of the Father’s praise, and when the believer is saved he/she is placed into Christ so the Father sees them through the prism of Christ.
Thought for consideration: this blessing always results in a holier life!
