What type of language do you use to thank God? Are your words plain and simple, direct and forthright? If you want others to understand how you feel about God and why you feel the need to thank Him, then you should say what is in your heart with emotion and love. In Psalm 145 the psalmist lays out his feelings about God, who He is and why God should receive his (ours too) thanks and praise.
I will extol you, my God and King,
and bless your name forever and ever. Eternal God and King
2 Every day I will bless you
and praise your name forever and ever.
3 Great is the Lord, and greatly to be praised, Unsearchable in His greatness
and his greatness is unsearchable.
4 One generation shall commend your works to another,
and shall declare your mighty acts.
5 On the glorious splendor of your majesty, Majestic, Wonderous
and on your wondrous works, I will meditate.
6 They shall speak of the might of your awesome deeds, Awesome deeds, His Greatness
and I will declare your greatness.
7 They shall pour forth the fame of your abundant goodness
and shall sing aloud of your righteousness. His Goodness and Righteousness
8 The Lord is gracious and merciful,
slow to anger and abounding in steadfast love. His Grace, Mercy, Patience and Love
9 The Lord is good to all,
and his mercy is over all that he has made. His Goodness and Mercy
10 All your works shall give thanks to you, O Lord, All Creation will give thanks to Him!
and all your saints shall bless you!
What an amazing list of attributes of our God! He is all those and so much more. Let your heart overflow with gratitude and thanks towards Almighty God!
