Jesus Christ is the light of the world (John 8:12).
He is God.
Those who know Jesus know God.
They have eternal life, which is knowing the only true God (John 17:3).
If they continue on with Jesus, they will live forever (John 6:51 & others).
Outside of Jesus, there is nothing.
Apart from Jesus, someone can do nothing (John 15:5).
Without Jesus, someone has nothing. Even if they gain the whole world, they possess nothing.
Without Jesus, a person is spiritually dead. If they die without Jesus Christ, they go to eternal death.
Eternal life continues forever in heaven, a place of absolute glory.
Heaven is God’s home, full of the glorious splendor of His majesty and infinitely more (John 14:2).
Those who know Jesus as Lord have the divine nature and life of God. They have the supernatural, abundant, zoe life. They have the Almighty God living in and through them – and all around them.
Those who know Jesus can accomplish things that will last forever. They can store up treasures in heaven, They can do even greater things than Jesus did (Matthew 6:19-21, John 14:12).

Eternal death continues forever in hell, the eternal fire prepared for the devil and his angels (Matthew 25:41).
