The defining characteristic of any member of the Remnant Church is made pretty clear in Revelation:
12:17And the dragon was wroth with the woman, and went to make war with the remnant of her seed, which keep the commandments of God, and have the testimony of Jesus Christ.
It is up to each of us to "study to show thyself approved before God".
I remember Elder Ralph Larson making the point rather pointedly that the Bible and the Testimonies to the Church were not just written for the church, they were written for ME!!! I must find the truth therein and apply it to myself.
You may want to read Hakim's thread on Dispensation. Very revealing and keeps us humble knowing we have inherited nothing, but must study to acheive atonement on our own. Each and every one, individually.
And if you know the commandments and have the Testimony, you will most surely want to share it. After all, just how many of your friends have no idea of that day or the hour in which we live?
Ever look at the obituaries and wonder if they even had a chance to know the truth? Ever wonder whether you should have done more to let someone know the commandments and to have lived as if you had the Testimony as an example to those within your realm of influence? That is the agony of the final tribulation. We will all have to live with the fact that probation, even for the living, is now closed and must wonder just what did we do to whom that may have cost them their eternal life.
When those concerns are real, you have acheived atonement with your Lord and Saviour and will live in the Spirit daily. You will emulate Christ.
And that is a GOOD Seventh-day Adventist.
