The last of the steps toward the loss of salvation does not get any easier. This step is based on your relationship to Christ at the time of salvation.

Romans 8:16-17 [16] The Spirit itself beareth witness with our spirit, that we are the children of God: [17] And if children, then heirs; heirs of God, and joint-heirs with Christ; if so be that we suffer with him, that we may be also glorified together.
See All... states:

The Spirit itself beareth witness with our spirit, that we are the children of God: And if children, then heirs; heirs of God, and joint-heirs with Christ; if so be that we suffer with him, that we may be also glorified together.

At salvation, you become a joint-heir with Christ. To be a joint-heir means to inherit together; to share in the same inheritance with which the Father will bless the Son. This is a promise of God.  

Yet, what if you lose your salvation and go to hell. As joint-heir, not only do you share in Christ’s inheritance, but He must also share in your inheritance. The only way for you to inherit hell and its horror is to take the Son of God with you to that awful place. That completes the fourteen steps toward loss of salvation.
