The man that wandereth out of the way of understanding shall remain in the congregation of the dead. Proverbs 21:16.
Remain on the way of knowledge that you may come into life. Eternal life is communicated through knowledge, the word of God, the knowledge of the truth. So also hell is communicated to man through knowledge.
Stay with the word of God, seek God’s knowledge, and retain it. That how eternal life is written in us.
