Since God is “a God of truth” (Deuteronomy 32:4), it makes sense that the words proceeding forth from His mouth would reflect and demonstrate the same nature as their author. According to the scriptures, this is exactly what has happened. The psalmist said, “thy law is the truth” (Psalm 119:142) “and all thy commandments are truth” (Psalm 119:151). The Lord Jesus confirmed this when He said, “Sanctify them through thy truth: thy word is truth” (John 17:17). If God is worthy of praise for being a God of truth, it only makes sense that His truth would also be worthy of man’s praise (Psalm 71:22). God, knowing this truth, magnified His word above all His name (Psalm 138:2).
Thankfulness strengthens and builds one's faith in the Lord. Christians need more outward and vocal expression of their thankfulness for God's provisions and blessings. Giving of thanks simply exalts the Lord. According to scripture, man can “magnify him [God] with thanksgiving.” Something magnified is made easier to see. Therefore, when men give thanks to the Lord, they make God more visible to a world overcome by sin. For what do you have to be thankful? Try giving God thanks for answered prayers, deliverance from trials, or simply His daily provisions. This thankfulness would help the world to see Him better. Ungrateful Christians have helped to convince the world that it does not need to give God credit for creation (and redemption among other things). Long before these perversions of truth, Christians ceased to give thanks.
