Eternal life!
But I can't divorce it from the rest of scripture. I have that eternal life because I have the Son and I abide in Him and He abides in me. It all began by this faith, this trust, this abiding. And just as it would be foolish to think I could finish in the flesh what began in faith and the receiving of the Spirit, it would be equally as bad to think it could be finished at all WITHOUT that faith, trust, abiding.
