Colossians 2:2b-3: . . . to the acknowledgement of the mystery of God, and of the Father, and of Christ; In whom are hid all the treasures of wisdom and knowledge.
God is Omniscient. That means He knows everything and has all wisdom.
1 Timothy 1:17: Now unto the King eternal, immortal, invisible, the only wise God, be honour and glory for ever and ever. Amen.
Wisdom is more valuable than knowledge. Wisdom is the ability to understand and apply knowledge appropriately. Knowledge without wisdom is useless. God knows what we need to know. He also wants us to know what we need to know. If we trust Him He will operate on a need-to-know basis with us. If we trust Him He will always tell us what we need to know. He will not necessarily tell me today everything that I need to know tomorrow. He will tell me what I need to know today. I can only trust Him one day at a time. In fact, I can only trust Him one moment at a time. Even though we know things that are ALWAYS His will, there are things we can only know one moment at a time. What specifically shall I do this moment? What shall I do five minutes from now? What shall I do tomorrow? We can only learn those specifics as we trust Him.
Matthew 6:34: Take therefore no thought for the morrow: for the morrow shall take thought for the things of itself. Sufficient unto the day is the evil thereof.
The verse does not mean that we should not plan ahead. The Bible teaches that we should plan ahead.
Luke 14:27-31: And whosoever doth not bear his cross, and come after me, cannot be my disciple. For which of you, intending to build a tower, sitteth not down first, and counteth the cost, whether he have sufficient to finish it? Lest haply, after he hath laid the foundation, and is not able to finish it, all that behold it begin to mock him, Saying, This man began to build, and was not able to finish. Or what king, going to make war against another king, sitteth not down first, and consulteth whether he be able with ten thousand to meet him that cometh against him with twenty thousand?
We should be willing to change our plans when God has a different plan. The first thing we should know every day is that we should trust the Lord. The second thing we should know is that we cannot trust ourselves.
Proverbs 3:5: Trust in the LORD with all thine heart; and lean not unto thine own understanding.
When we trust the Lord and not ourselves He will teach us what we need to know for each day. The first part of every plan should be to trust the Lord and seek His direction. Then we will get His direction. The natural result will then be trusting the Lord enough to do or say what He wants. The moments when we trust in something or someone other than God, such as our own understanding, we can go astray.
A god who would expect us to obey him if He didn*t tell us what to do would be a stupid god. Our God is All-Knowing and All-Wise. Whenever we trust someone or something other than the God of The Bible we lose access to His knowledge, wisdom and guidance. We need to listen to The God That KNOWS. We need to listen to The God who is NEVER wrong.
Proverbs 21:30: There is no wisdom nor understanding nor counsel against the LORD.
