A rich man once asked a simular question of Jesus, he asked: "Teacher, what good things must I do to have eternal life?"
Jesus said to this man: "Why ask me about what is good? Only God is good. But to answer your question, you can receive eternal life if you keep the commandments."
"Which ones?" The man asked.
And Jesus replied: "Do not murder. Do not commit adultery. Do not steal. Do not testify falsely. Honor your father and your mother. Love your neighbor as yourself."
"Ive obeyed all these commandments," the young man replied. "What else must I do?"
Jesus told him, "If you want to be perfect, go and sell all you have and give the money to the poor, and you will have treasure in heaven. Then come and follow me."
But when the young man heard this, he went sadly away because he had many possessions.
(I believe this goes hand and hand with this scripure):
Jesus replied: "The most important commandment is this: 'Hear O Israel! The Lord our God is the one and only Lord. And you must love the Lord your God with all your heart, all your soul, all you mind, and all your strength. The second is equally important: 'Love your neighbor as yourself. No other commandment is greater than these."
(33. This is more important than to offer all of the burnt offerings and sacrifices required in the law).
Just imagine that type of love. I dont believe any of us have ever to date aside from Jesus have ever comprehended that type of love. Not even in our wild imagination. Not with our husbands, wives, children, brothers, sisters, mothers, or fathers, has any of us ever so loved another.
So to your question: How do you give your all to Jesus?
By believing.
(Sounds easy enough dont it. Try it sometime. In everything you do apply scriptures, try believing them for your situation. If God tells you something is true, believe it. Believe me, satan will be there to try and get you to doubt.
I have an cute example from family life. My brother has me run errands for him all the time. Once he asked me where I got his dip for him. So I told him, but he didnt believe me. I was like, why did you ask me if you arent going to believe me? Did you think I was going to lie to you? That is where I got it from! Crazy thing is he is always doing that to me, and I have never lied to him.
It must just be something about some peoples nature, I dont know??? But anyways, it reminds me of what we do to God. Why do we ask God and then not believe him. We need to start believing God, take him at his word. God does not lie).
If we go back to the book of Genesis, now this is just me, isnt all God ever asked from us is that we believe? I have given all these trees to eat from, just dont eat from this one, if you do you will die. -Sounds like, hey just believe me- dont it?
Then Jesus comes, For God so loved the world he gave his only begotten Son that whosoever believes in him will not perish but have everlasting life.
Just believe.
If you want to live-believe!
Quit doubting and believe!
