"Excessive planning: attempting to control what will happen...is a commonly practiced form of unbelief... I did not design the human mind to figure out the future... I crafted your mind for continual communication with Me. Bring Me all your needs, your hopes and fears... Turn from the path of planning to the path of Peace." (272)
Certainly the Bible supports wise planning - "The plans of the diligent lead surely to advantage." (Prov. 21:5) - but it's the excessive, compulsive desire to control our future that can lead to unbelief, worry and unhealthy tendencies that enslave us. I suppose our compulsive planning is really a desire to somehow 'fix' the future. It is an attempt to insulate ourselves from possible impending pain. However, living without peace is the most painful kind of existence.
I like the Jeremiah 29:11 passage that reminds us how the Lord has plans for our welfare and our future. His plans will not bring disaster but a hope!
Psalm 37:3-5 sums it up well - Trust in the Lord and do what is good; dwell in the land and live securely. Take delight in the Lord and He will give you your heart's desires. Commit your way to the Lord, trust in Him and He will act."
"And the peace of God, which surpasses every thought, will guard your hearts and your minds in Christ Jesus." (Phil. 4:7)
