Concerning Matthew 13, where Christ says that He has spoken in parables in order that there will be those that will see, "and yet they will not see. They will hear, but will never understand." In other words God has hidden truth from certain individuals.
The question really is why would God do this? This doesn't seem fair, if they were really seeking for Christ? Can we seek after him or does he seek after us? What's the purpose of parables ?
I don't think that God is not hiding information from those who are really seeking Christ in respect to those who have humbled themselves before God and realize their spiritual bankruptcy, and cry out to God for mercy, and in faith trust that what God has declared is true and trustworthy. I believe God the Holy Spirit will open their eyes, give them ears to hear what the Spirit is saying and they will by faith see the truth.
It would seem from my experiences that most of the people of the world think they are wiser than God in their own eyes. They really believe that they can know truth, that they can decide what is true or what is not true. They are not ready to humble themselves. They are ready to pick and choose from the Bible what they want or what they don't want. In other words, they want to design a religion that meets their specifications rather than those of God.
The reason God hides knowledge from people is because they are rejecting the love of His truth.. God knows when a person is not going to accept the way of salvation His has mades to save people.. Therefore He hides from them the deeper knowledge of salvation and sends then strong delusions so that they will be decieved and will be condemned.. But those who are accepting and will meekly accept the Way of salvation with contrition He will lead them into the wisdom they need to know to be saved.. The following scripture is important to take in..
I quote the chapter to give context to the message::
2 Thessolonians 2 KJV
Now we beseech you, brethren, by the coming of our Lord Jesus Christ, and by our gathering together unto him,
2 That ye be not soon shaken in mind, or be troubled, neither by spirit, nor by word, nor by letter as from us, as that the day of Christ is at hand.
3 Let no man deceive you by any means: for that day shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition; 4 Who opposeth and exalteth himself above all that is called God, or that is worshipped; so that he as God sitteth in the temple of God, shewing himself that he is God. 5 Remember ye not, that, when I was yet with you, I told you these things?
6 And now ye know what withholdeth that he might be revealed in his time. 7 For the mystery of iniquity doth already work: only he who now letteth will let, until he be taken out of the way. 8 And then shall that Wicked be revealed, whom the Lord shall consume with the spirit of his mouth, and shall destroy with the brightness of his coming: 9 Even him, whose coming is after the working of Satan with all power and signs and lying wonders,
10 And with all deceivableness of unrighteousness
in them that perish; because they received not the love of the truth, that they might be saved. 11 And for
this cause God shall send them strong delusion, that they should believe a lie: 12 That they
all might be damned who believed not the truth, but had
pleasure in unrighteousness.
So if people are rejecting the love of the truth,, which is the way of salvation by the loving Atonement of the LORD Jesus Christ then those people will not only be blocked from deeper truths and wisdom of scripture they will be send strong delusions so that they will believe in deceptions and they will have no hope but will be condemned..
