Any group that acknowledges Jesus Christ as God, and which reads the Word for guidance in their daily life, is the Lord's true Church. There are hundreds of passages in the Old and New Testaments that teach about the nature of the judgment to come. Many of them specifically say that each will be rewarded according to their works, their acts of charity in this world. Not a single one says that anyone will be rewarded for their faith alone. Obey the 10 Commandments, turn away from the love of the world, do good to others, and to do all those things for the Lord's sake.
Faith only enters into it in the fourth point.
The young man, and by analogy each of us, was to obey the other commandments not because they were to our benefit, not for selfish reasons, but because the Lord asks it of us. From the evidence of the gospels, and the letters which they wrote to one another as they struggled to find forms appropriate to these new teachings, it is apparent that they believed that to be a Christian was to follow the teachings and example of Christ. The early Christian Church, when it was in its integrity, did exactly that. One of the most persistent doctrinal issues in the short history of the New Church has been the issue of whether the spiritual truths revealed through Emanuel Swedenborg were to be the foundation of a new church, or whether they were to enlighten and revitalize the old. The early readers of Swedenborg argued that since there is nothing in the whole of the Writings that speaks directly of the earthly form of the New Church, and the fact that Swedenborg himself was a member of the Lutheran Church until his death, that there was no reason for there to be a distinct and separate New Church organization.
