Jehovah's Witnesses and salvation

Jehovah's Witnesses believe salvation is a gift from God attained by being part of "God's organization" and putting faith in Jesus' ransom sacrifice. They do not believe in predestination or eternal security. They believe in different forms of resurrection for two groups of Christians: that the 144,000 members of the anointed will be rulers in heaven and that "the other sheep" or "the great crowd" will live forever on earth.
