People will sometimes keep a prized possession out of harm's way to such an extent that they no longer use it or enjoy it. Fortunately, Christians can rejoice in the knowledge that the forgiveness of sins, their relationship with God, and their eternal hope can never be taken away. Few truths are as beautiful as God's promise that those who are born again receive a permanent birth and can never lose their status as His sons and daughters.",
