Colossians 2:2 that their hearts may be encouraged, being knit together in love, to reach all the riches of full assurance of understanding and the knowledge of God’s mystery, which is Christ, in whom are hidden all the treasures of wisdom and knowledge. I say this in order that no one may delude you with plausible arguments.
Romans 11:33 Oh, the depth of the riches and wisdom and knowledge of God! How unsearchable are his judgments and how inscrutable his ways!
2 Timothy 3:15-17 and how from childhood you have been acquainted with the sacred writings, which are able to make you wise for salvation through faith in Christ Jesus. All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness, that the man of God may be complete, equipped for every good work.
1 Corinthians 2:6-7 Yet among the mature we do impart wisdom, although it is not a wisdom of this age or of the rulers of this age, who are doomed to pass away. But we impart a secret and hidden wisdom of God, which God decreed before the ages for our glory.
Matthew 10:26 “So have no fear of them, for nothing is covered that will not be revealed, or hidden that will not be known.
Ephesians 3:9 and to bring to light for everyone what is the plan of the mystery hidden for ages in God, who created all things,
Colossians 2:8 See to it that no one takes you captive by philosophy and empty deceit, according to human tradition, according to the elemental spirits of the world, and not according to Christ.
2 Thessalonians 2:9-11 The coming of the lawless one is by the activity of Satan with all power and false signs and wonders, and with all wicked deception for those who are perishing, because they refused to love the truth and so be saved. Therefore God sends them a strong delusion, so that they may believe what is false,
For Paul, real riches were found in the believer’s full assurance. Many lack full assurance about the character of God and are unconvinced that He is really good and loving. Others lack full assurance of their salvation and wonder if their Christian life is for real. Great freedom and confidence comes when we come to this full assurance. “You will only find all the treasures of wisdom and knowledge in Jesus. He has them all.” It’s not wrong to seek after wisdom and knowledge; but we must seek it all in Jesus. Real wisdom is not hidden in secret books, but deposited in Jesus Christ so that all can access it. When Paul describes the truth of God with words like riches and treasures, he reminds us that God’s truth is precious and worthy of sacrificial seeking. (Guzik)
It might sound simple, but deceivers are deceivers. They won’t announce their false doctrine as false doctrine, and it will often be similar enough to the truth to be dangerous. Combining The Word of God with worldly knowledge and wisdom will never end well. Dilution of God’s Word will never lead us into deeper understanding, knowledge, and wisdom. On the contrary, it will confuse, weaken, and leave us unsatisfied. We never obtain complete wisdom, knowledge, and understanding but we certainly will grow and mature in it for our entire lives. Line upon line, precept upon precept, here a little and there a little, we will mature if we are diligent in our intentional choice to humbly seek, surrender, obey, follow, trust, and rely on and in Jesus Christ, the mystery of God to man.
