To those of us who have insight to reality, see things for what they are, and have a passion of exposing those things to warn others, we have one specific purpose. However, there are two sets of people in this and they are diverse.
One set is the Awoke who do not have religion, do not have a Christian faith, could even be Atheist, or perhaps have New Age philosophy of karma, so their hope is in changing the world and emphasizing the need to know as to shout to people to guard themselves and change the outside if they can. To them everything is dependent on KNOWING.
Then there is the Christian truther. They can get trapped into forgetting they have a transcending hope. Yes we grieve like the others, yet don’t grieve as those without hope. For us, we live in this world, the same things affect us in this world, we would like to have them changed, BUT our hope isn’t IN this world. We preside in a different kingdom and have our eyes on the eternal prize. Our purpose isn’t just warning people of the external woes, we also help them see the spiritual to trust in the Savior and be changed internally. Thus also having an eternal life secure by believing (trusting fully) in Jesus Christ. We recognize salvation isn’t knowing these other things, but they can lead us to telling our hope and witnessing who we trust in.
The means may be the same, but the end purpose is a bit different between the two. Anyone who claims to be a Christian Truther should regard what I am trying to say.
