God created humanity in a way that is very different from the way God created the world. This is the core of Christianity: that God loved the world enough to come as Jesus and to die for us, so that anyone who trusts in Him will be saved from sin. This verse is a one-sentence summary of the gospel and the subject line of the entire Bible. Jesus is an expression of God's indescribable, Unfailing love for the world.The life offered to those who believe in Christ is "eternal"...NEVER ENDING. The alternative to life in Christ is destruction: to perish.There is no question that, according to the Bible, people can be saved only through faith in Jesus.
For God so loved the world that He gave his only begotten son, that whoever believes in Him should not perish but have everlasting life. (NKJV)
