John 3:16 For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.
All who believe in Christ---come to Him in repentance---are promised everlasting life. This is a powerful phrase. It literally means what it says to those who believe.
We shall never perish, be put away or rejected. We shall live forever in the presence of our blessed Lord and Savior.
2 Peter 3:9 The Lord is not slack concerning his promise, as some men count slackness; but is longsuffering to us-ward, not willing that any should perish, but that all should come to repentance.
There are a lot of decisions that we make in life, but none are as important as the decision we make concerning Christ----to believe or not to believe. That decision will remain with us throughout eternity.
