Why is being in Christ necessary for blessings?

The necessity of being in Christ for receiving God’s blessings stems from the understanding that true righteousness and holiness can only be found in Him. As stated in the sermon, the blessed man is ultimately Christ, who fulfilled every aspect of the law perfectly. When one is in Christ, they are united to Him and thus share in His righteousness. Therefore, outside of Christ, one cannot claim any true blessing or favor from God, as all human efforts are insufficient for salvation and divine acceptance.
