Our salvation depends solely on the real and forever living Christ Jesus. We get saved (Matt 11:28-29; 19:21) only by and through abiding in and following Jesus unto the end (John 15; Matt 11:28-29; 19:21). But our salvation gets lost the moment we stop abiding in and following the Lord Jesus (John 15:2, 6). Therefore, abiding in and following Jesus unto the end is the only assurance of our salvation.
