We have seen in Colossians Chapter one that we were chosen by the Father, redeemed by the Son and sealed by the Holy Spirit.  Concerning our having been chosen by the Father, Vs. 5 says,
“having predestined us to adoption as sons by Jesus Christ to Himself, according to the good pleasure of His will”  
 
Let’s see what Scripture tells us about predestined/predestination; God’s eternal plan-- 
“Who has saved us and called us with a holy calling, not according to our works, but according to His own purpose and grace which was given to us in Christ Jesus before time began.”  
2 Timothy l:9 
 
Romans 8:28 say there is a purpose (we all know this verse well!),
“And we know that all things work together for good to those who love God, to those who are called according to His purpose.”
 
Planned beforehand, Romans 9:23-24,
“That He might make known the riches of His glory on the vessels of mercy which He had prepared beforehand for glory, even us who He called…” 
 
Scripture tells us in Romans 9:29 the purpose,
“For whom He foreknew, He also predestined to be conformed to the image of His Son, that He might be the first born among many brethren.”
 
Ephesians 3:1-12 tells us of the mystery of the church, 
“Which in other ages was not made known to the sons of men, as it has now been reveled by the Spirit to His holy apostles and prophets; that the Gentiles should be fellow heirs of the same body, and partakers of His promise in Christ through the gospel.”  Vs.5-6
 
Not only the Jews, but all nations, the gentiles, 
“Therefore know that only those who are of faith are sons of Abraham.  And the Scripture, foreseeing that God would justify the nations by faith, preached the gospel to Abraham beforehand, saying, ‘In you all nations shall be blessed.’  So then those who are of faith are blessed with believing Abraham.”  
Galatians 3:6-9
 
God accomplished this,
“According to the eternal purpose which He accomplished in Christ Jesus our Lord.”  
Ephesians 3:11
 
God’s plan was set forth in the counsel of eternity past  and continues today.  His plan will be accomplished and complete at the end of time!  
 
“Whom He predestined, these He also called; whom He called, these He also justified; and whom He justified, these He also glorified.”  
Romans 8:30
 
Knowing this how can we not hunger and thirst to know God; Father, Son and Holy Spirit more and more.  We are His and He is ours.  Imagine!  The Creator of all things loves us beyond our finite comprehension.  Words fail at the awesome knowledge that He who created ALL THINGS is our Father!
