His ways are always higher than our ways and to know His ways is to understand His Word.
For the word of God is living and powerful, and sharper than any two-edged sword, piercing even to the division of soul and spirit, and of joints and marrow, and is a discerner of the thoughts and intents of the heart.
Because the Word of God is able to discern which is the decision of the soul (mind and emotions) and which is according to the Spirit.
While God is not saying you can’t think for yourself but what He is saying through His Word is that He loves you more than you can ever love yourself so the guidance of His Spirit and Truth is always for our best interests, for the best results to be enjoyed.
Faith is not found in the wisdom of Man (self-reliance) but in the Power of God (Spirit-reliance) To get the God-kind of results is to invest in the God-kind of seed which is His Word and promises.
So the key to submitting our decisions to the Lord is to get Him involved in your decision-making, discern through His Word and Spiritfor specific revelations to apply in your specific situations and to rest in His reassurance that He will perform on your behalf.
To rely on your own understanding is to rely on self-performance but to rely on His understanding is to trust in His performance.
Just remember this that the Word of God is given not to limit us but help to maximize the best out of our abundant life in Christ :)
