4 Enter into His gates with thanksgiving, and into His courts with praise. Be thankful to Him, and bless His name. 5 For the Lord is good; His mercy is everlasting, and His truth endures to all generations. (Psalm 100:4–5, NKJV)
Psalm 100 is a psalm of thanksgiving unto God. All the earth is pictured as serving the Lord with gladness, and coming “before His presence with singing” (Psa. 100:1-2). God is due the service of worshipful praise because He is our Sovereign, our Creator, and our Sustainer (Psa. 100:3-4). The blessings that come to us from Almighty God also inform and persuade our thankful worship of Him. Three of God’s character traits, from which our blessings flow, are highlighted as reasons for giving Him thanks. 1) His goodness. In His beauty, God showers good blessings on us all (Acts 14:17). 2) His mercy. God is unfailing in His kindness and ever vigilant to show mercy “to thousands, to those who love Me and keep My commandments” (Exo. 20:6). 3) His truth. Unfailing in its power to purify us, God’s word of truth endures forever (Jno. 17:17; 1 Pet. 1:22-25). God’s goodness, mercy, and truth compel us to “enter His gates with thanksgiving” with joyful praise. May we always give God thankful praise for who He is and for what He does for us.
