John 3:16, “God loved the world so much that He gave His only begotten Son, Jesus Christ, so that whoever believes in Him shall not perish but have everlasting life.”

Romans 6:23, “But now that you have been set free from sin and have become slaves to God, the fruit you reap leads to holiness, and the outcome is eternal life. 23For the wages of sin is death, but the gift of God is eternal life in Christ Jesus our Lord.

Well was does everlasting life and gift of eternal life mean in this context?
