The metaphor of the house and mansions seems to me to mean we go through a narrow door—full devotion to Him—and enter a wide place, with “room for all who come.”
Salvation is of the spirit, so our spirit must turn toward Him completely before we die. Beware of the pagan-like images of streets paved with gold and wings and halos and harps. If we have done even one tiny thing solely for Jesus, we have eternal life. Even if we don’t but want to and don’t have the time (deathbed conversion).
This is what it means to me.
Start at the six-minute mark, unless you want to hear all the news about their new church and their trip to Israel.
