Eternity is a very long time...
We all make decisions as to how we live our lives, but what if the decisions we make now actually had a bearing on our eternal life. While as Christadelphians, we don't hold the commonly held beliefs in a physical place called 'heaven' or 'hell' that we go when we die, we do believe that we all have the capacity to influence our own eternity. It can be an eternity of death or it can be an eternity spent with God.
Many people live their lives as if there is no tomorrow, pleasing themselves, accumulating wealth and possessions, with no concern for what the long-term future holds. Choosing our eternity is a novel concept to most, however unless we decide now, nothing we have or are will last beyond the few short years we have on earth.
