How much do you trust what you believe? When it comes to where you spend the next hundred billion years and if it will be with God, the deciding action word is believe. It is the life-or-death verb.
Don't just believe intellectually, but with everything you have. Believe with a life-long commitment.
In Acts 16:30-31 from God's Word, a man asks the great missionary Paul the timeless question, "What must I do to be saved?" The answer is clear and unmistakable, "Believe in the Lord Jesus, and you will be saved." Obviously, saved is a life-or-death word. Just ask the people who were saved from the Federal building in Oklahoma City or someone who was saved by an emergency medical team. If the rescuer saves you, you live. If he doesn't, you die.
The kind of saving the Bible talks about is being rescued from the death penalty we are all under with God. The Bible says, "All of us have wandered away like sheep; we have turned each one to his own way" ( Isaiah 53:6). That's your way instead of God's way and ultimate rebellion against the ultimate authority. He is the One who gave you your life to live for Him.
The death we suffer in this life is trying to live without God's love, God's peace, and without God's purpose for our days. If we die without Him, the penalty is what the Bible calls hell.
That is where believing in Jesus comes in. He is the only Rescuer and the only Savior that can keep you from dying spiritually. He died on the cross to bear all the guilt and penalty of the sins you've committed. That's how much He loves you. If you're going to be saved, you must "believe in the Lord Jesus."
The Bible says in Romans 10:10, "It is with your heart that you believe and are justified." You must believe in Jesus with your head and your heart to be made right with God. That means committing yourself in total trust to the One who died in your place.
Has there ever been a time in your life when you told Jesus, "I'm putting all my hopes in you and what you did on that cross to rescue me from my sin." If there's never been a time like that, you are in eternal danger. That could change in the next few minutes if you would reach out to this Savior you've known about, but have never really known in a personal relationship. He can be trusted with your life.
