"O LORD, Thou art my God;
I will exalt Thee, I will give thanks to Thy name;
For Thou hast worked wonders,
Plans formed long ago, with perfect faithfulness."  Isaiah 25:1

Is it not an awesome wonder to realize that any of us can say 'Lord, Thou art my God'?
We who were the very enemies of God.  We who 'were dead in our trespasses and sins'.  We who 'were darkness'.  We who were hopelessly lost.  Should we not, therefore, continually give thanks to God for His grace and mercies which He purposed in eternity past?

By His lovingkindness and tender mercies and glorious grace, He sent Jesus Christ, His Son into the world to reconcile us to Himself while we were yet His enemies.  It takes the whole Godhead to bring us to that position.  First we had to come to the place of seeing our desperateness; sinful and lost, needing a savior.  It was God who enlightened the eyes of our understanding to see ourselves as we really are, if He had not done so we would have gone just as we were.  Jesus came to die to pay the penalty for sin (my sin and yours) so that 'whosoever  believes in Him shall not perish but have eternal life'. 

Now we have the Holy Spirit who leads and gui8des us here on earth so that we can live that new life in Christ in a manner worthy of God.
"...The love of God has been poured out within our hearts through the Holy Spirit who was given to us."  Romans 5:11
Therefore, we can say with awe, 'For Thou hast worked wonders'.

"Plans formed long ago, with perfect faithfulness, 
The plans of His heart from generation to generation
Blessed is the nation whose God is the LORD,
The people whom He has chosen for His own inheritance."  Psalm 33:11-12

"Also, we have obtained an inheritance, having been predestined according to His purpose who works all things after the counsel of His will."  Ephesians 1:11

How can we not continually in awesome wonder, exalt Him and give thanks to His name! 

""Enter His gates with thanksgiving,
And His courts with praise.  Give thanks to Him, bless His name,
For the LORD is good;
His lovingkindness is everlasting,
And His faithfulness to all generations."  Psalm 100:4-5
Amen
