Jer 10:23
(23) O LORD, I know that the way of man is not in himself: it is not in man that walketh to direct his steps.
Psa 37:23
(23) The steps of a good man are ordered by the LORD: and he delighteth in his way.
Rom 8:13-14
(13) For if ye live after the flesh, ye shall die: but if ye through the Spirit do mortify the deeds of the body, ye shall live.
(14) For as many as are led by the Spirit of God, they are the sons of God.
all that a man achieves that is good is the direct result of his being led by God's thoughts, and all that he fails to achieve that is good is the direct result of being led by his own thoughts. the flip side - all that a man achieves that is bad is the direct result of his being led his own thoughts, and all that he fails to achieve that is bad is the direct result of being led by God's thoughts.
