1) We cannot presume to know what will happen tomorrow and should submit our plans to God's will. 2) God warns that pursuing our own desires often leads to frustration, as He may intervene and bring about a different outcome. 3) To discern God's will, we must deepen our relationship with Him through obedience to His word, transforming our minds and not conforming to the world. Submitting our plans to Him allows His will to be fulfilled.
