I have some realatives who formerly were members of thel SDA Church but have not been for years. For a number of years they have not been associated with any denomination or church. Recently they have become quite interested in a well-known evangelist, not SDA, who is preaching several unique SDA Doctrines, but not the Sabbath. When he comes to their area, they travel to wherever he is to hear him. As a result they have recently began attending, on Sabbath, a local church (not SDA) that has services on Sabbath and on Sunday.
I cannot help but believe that the Holy Spirit is leading in these events. I trust in God that the HolySpirit will continue to lead. I am willing to wait to see how that goes and the direction that it takes.
The bottom line is that some SDA congregations are not a place where some people can grow spiritually. In such places it just may be that the Holly Spirit would lead these people to a non-SDA congregation where they cold grow spiritually. Doing so, I assume that the Holy Spirit would continue to lead these people in the spiritual direction that God would want them to go. Who knows, if a local SDA congregation was able and willing to assume the role that God would want of it, these people just might be led to this congregation.
We may be in the "last days." But, in my opinion, we are not yet at the place were the people of God are all in one denominational organization. As I said in another post. When the time comes where the people of God are united in belief, there will not be any organized SDA Church.
