God doesn't want you to worry about anything. God wants you to enjoy His peace every minute of the day as long as you live. He wants you to possess His peace and learn how not to worry. One way to do that is by controlling your thoughts.

Keeping Your Thoughts Under Subjection
Consider this passage in Corinthians:

Know ye not that the unrighteous shall not inherit the kingdom of God? Be not deceived: neither fornicators, nor idolaters, nor adulterers, nor effeminate, nor abusers of themselves with mankind, nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners, shall inherit the kingdom of God.
(1 Cor. 6:9-10)

God said the path to heaven is narrow. You can't live a loose life and get to heaven.

Enter ye in at the strait gate: for wide is the gate, and broad is the way, that leadeth to destruction, and many be there which go in thereat: Because strait is the gate, and narrow is the way, which leadeth unto life, and few there be that find it.
(Matt. 7:13-14)

But God has made you a promise. He says everything that you bind in Jesus Christ's name will be bound in heaven. For example: "...and whatsoever thou shalt bind on earth shall be bound in heaven (Matt. 16:19).

Choose To Live For God
It is up to you to stop anything that is not good for you. It is not up to God to stop it.

The easiest thing for a person to do is to go to hell. All you have to do is reject this truth: A person must confess his sins and accept Jesus Christ in his life in order to be saved.

According to Romans 10:9-10, a person must confess with his mouth the Lord Jesus and believe in his heart that God raised Jesus from the dead; then he will be saved.

For with the heart man believes unto righteousness; and with the mouth he makes confession unto salvation. Only then is he able to go to heaven.

All you have to do to get into hell is to do your own thing. That is not hard. Just slide around, kind of loose, and do what you want to do. Reject Jesus and hell is where you will wind up.

When you take your last breath, your spirit—the real you—is going to come out of that body. If you have bowed before God, accepted Jesus Christ in your life, and the blood of Jesus has washed all your sins away, you can stand before God as white as snow.

Luke 16:22 says that when the beggar Lazarus died, he was carried by the angels into Abraham's bosom. When believers in Jesus Christ die, don't you think that the angels carry them all the way to heaven?

You Belong To God Now
When you die, the angels will be standing there waiting to take your spirit to heaven because they will have the right to it. All the demons of hell roaming back and forth through the air simply cannot keep the angels from taking your spirit.

Why? Because you belong to God. If you have accepted Jesus Christ, Jesus said you shall be saved.

To him that overcometh will I grant to sit with me in my throne, even as I also overcame, and am set down with my Father in his throne.
(Rev. 3:21)

But if you have done your own thing until you die, if you have rejected Jesus Christ and pushed Him out of your life, you spirit will not go to heaven. You will go to hell for eternity.

When I asked Jesus why people choose to do their own thing instead of following Him, He said, "Because they need to be filled with the Holy Spirit." You need to be filled with the Holy Spirit. If you keep yourself full of God, your mind will not get confused.

If you want to maintain your mind free and clear, remember that whatever goes in you will come out. If you watch programs that portray adultery and other temptations, your mind will start thinking about those things and you will compromise your beliefs.

But if you put the Word of God in you, the peace of God will be manifested in you—all over your body, all over your mind. You will be strong.

There will be no place for weakness. God wants His children to be strong to fight the devil.

You must always remember that you are in a battle with the devil. He hates you. He will tempt you with everything he can. If you give into his temptation, your faith will crumble, and you will wonder why your mind is so confused.

When you separate yourself from God and backslide, you become so burdened that life becomes unbearable. You lose fellowship with the Lord. You depart from His glory.

Therefore, get down on your knees before God and repent. He will restore you.
