Essentially people should praise God because He is who He is. Two of the outstanding qualities that God demonstrates are loyal love and truth. His loyal love (Heb. hesed) to His people is very great, and His truth continues forever. Human loyalty often has limits, and we are not consistently truthful. The Hebrew word translated "truth"is emetthat the translators frequently render "faithfulness."The relationship between these two English words is clear. Because the Lord is true He is a faithful God. Hesedand emetoften occur together in the psalms. God's faithfulness connects closely with His loyal love. This psalm closes as it begins with an exhortation to praise the Lord.
Outstanding among all God's great qualities are His loyal love and faithfulness. His people should honor Him for these traits consistently and frequently.
