There are four things you need to know to be sure of eternal life in heaven:

1. We are sinners.
“For all have sinned and come short of the glory of God.” (Romans 3:23)

According to that verse, I am a sinner.
And according to that verse, you, too, are a sinner.

Sin is breaking God’s law. It is doing something God said not to do or not doing something God said to do.

2. The penalty for sin is death.
“The wages of sin is death… “(Romans 6:23a)

Some people think that if they do more good than bad they will go to Heaven. But the Bible does not say that the wages of sin is to be good. The bible says that the wages of sin is death.

Others believe that they will go to Heaven because they were baptized. But the Bible doesn’t say that the wages of sin is baptism. The Bible says that the wages of sin is death.

Some people say, “Ours is the one true church.
If you join our church you will go to Heaven.
“But the Bible does not say that the wages of sin is to join a particular church. The Bible says that the wages of sin is death.

If we pay what we owe for our sin, we must die and spend eternity in Hell.

3. Jesus paid the penalty for us.
“But God commendeth His love toward us in that while we were yet sinners, Christ died for us. “(Romans 5:8)

Jesus Christ is God the son. He is as much God as if He had never been man, and as much man as if He had never been God. After living a sinless life, the Lord Jesus went to the cross were He bled and died for our sins. After three days in the tomb, He rose from the grave, proving His power over death, sin, and Satan. The wages of sin is death. Jesus died for us; so He paid the wages of sin.

4. We must accept His payment for us. The wages of sin is death, but the gift of God is eternal life through Jesus Christ our Lord.” (Romans 6:23)

A gift is always free. If I pay even a fraction of it’s value it is no longer a gift. Eternal life is life forever in Heaven. This gift is available only through the Lord Jesus Christ.

Romans 10:13 tells us how we can accept God’s wonderful gift of eternal life.
“For whosoever shall call upon the name of the Lord shall be saved.”

To be saved, we would have to be saved from something. If I were drowning and you threw me a rope; I would say that had saved me from drowning. When we pray and ask the Lord Jesus to save us, He saves us from our sin and the penalty of death in Hell.
