As for God, His way is perfect! The word of the Lord is tested and tried; He is a shield to all those who take refuge and put their trust in Him.

(Psalm 18:30)

The greatest form of faith that pleases and moves God Almighty is the prayer of thanksgiving. When you thank God in advance you are acknowledging that Jesus Christ is Lord over your life and you believe His Word.  True faith and reliance on God Almighty always thanks Him in advance because you know He is true to His Word and promises.

Be anxious for nothing, but in everything by prayer and supplication, with thanksgiving, let your requests be made known to God; and the peace of God, which surpasses all understanding, will guard your hearts and minds through Christ Jesus.

(Philippians 4:6-7)

When you read the gospels you see this was the way Jesus prayed to the Father God.  He would always thank Him in advance.  We have so much to thank Him for.  He is a wonderful and awesome God who loves you over flowing.  It is His joy to see you prosper in all that you do.

And those who know your name will put their trust in You; For You, LORD, have not forsaken those who seek You.

(Psalm 9:10)

So we, Your people and sheep of Your pasture, Will give You thanks forever; We will show forth Your praise to all generations.

(Psalm 79:13)

And He took the seven loaves and the fish and gave thanks, broke them and gave them to His disciples; and the disciples gave to the multitude.

(Matthew 15:36)

Then He took the cup, and gave thanks, and gave it to them, saying, “Drink from it, all of you.

(Mat 26:27)
