The Romans Road

The Roman Road, e.g., the pathway of salvation, was not constructed for people to escape to heaven, although used for that purpose. Instead, its purpose is to bring heaven into you right now. God desires to fill you with heaven, not fill heaven with you. Jesus explicitly states in this verse that we should pray for the kingdom to come. He did not say anything about praying for the great escape.

Matthew 6:10 KJV

(10) Thy kingdom come. Thy will be done in earth, as it is in heaven.

Being filled with heaven now, assures us of being in heaven forever.
