We don’t know everything that went down with Lucifer prior to his fall from Heaven, but the Book of Isaiah provides us an idea of what led to his downfall:
“How art thou fallen from heaven, O Lucifer, son of the morning! how art thou cut down to the ground, which didst weaken the nations! For thou hast said in thine heart, I will ascend into heaven, I will exalt my throne above the stars of God: I will sit also upon the mount of the congregation, in the sides of the north: I will ascend above the heights of the clouds; I will be like the most High (Isaiah 14:12-14 KJV).”
In short, Satan has an I problem. He thinks of himself, and only himself, hence his sounding like a child screaming “I will, I Will, I WILL!”
As for Jesus, He thinks of others. Why? Because it’s God’s will (Luke 6:31). In fact, Jesus teaches us in The Lord’s Prayer to acknowledge God’s will:
“Our Father which art in heaven, Hallowed be thy name. Thy kingdom come, Thy will be done in earth, as it is in heaven (Matthew 6:9-10 KJV).”
In the moments just before He was arrested, Jesus once again acknowledged God's will:
"...Father, if thou be willing, remove this cup from me: nevertheless not my will, but thine, be done (Luke 22:42 KJV)."
Think for a moment how you have behaved in recent days, weeks, months, or maybe most of your adult life. Did you or do you often think only of yourself? When was the last time you acknowledged God’s will?
You can’t change what you’ve done wrong. But you can determine what happens for the rest of today and tomorrow.
