I grew up with Christian parents and my life revolved around church, but as a high school senior I encountered atheism when a friend became an atheist and my favorite teacher had been a minister but was agnostic. This prompted me to search Scripture for answers that the pastor's weekly sermons about how to be saved had not taught. Eventually I felt led to become a minister in order to share the answers I found with Christians who might witness to atheist friends or at least be edified and not deceived by their argumenta. As a military chaplain I debated atheists on the AKO online forum, and I was invited to speak at a meeting of the atheists in Austin. Now that I am retired, I would like to pass on what the Lord has taught me before I die to those on CC. I have a similar hope with regard to people claiming to be theists and Christians who have heretical beliefs, so I amended the OP to include them.
I began philosophically like Rene Descartes (d.1650) by exploring whether there is some truth everyone affirms at least implicitly and uses as a common point of departure in discussing ultimate reality, and I proposed three axiomatic truths that even skeptics talk as though they assume: 1. the reality of the student, 2. finite human beings cannot know absolutely, infallibly, perfectly or objectively as David Hume (d. 1776) opined (cf. 1Cor. 13:9&12, 2Cor. 5:7), and 3. uncertainty does not prevent knowledge with sufficient confidence even when communicating doubts. Thus we all ought to be willing to witness with the understanding that truth is believable, rational and meaningful, even though unprovable or subjective. In the words of Isaiah 1:18a (c.735 B.C.), “Come now, let us reason together.” Discussion of ultimate reality uses a common language as the means, and I hope English will suffice for you and me.
Believing that truth is unified and so it does not matter much where discussion begins, I sought to discern the logical point from which the varieties of beliefs extant in the world diverge. Although only a newborn begins with a blank slate, I began by being unbiased and imagining that I suddenly began to exist as an adult human being, like Adam and Eve in Genesis. I guessed that my immediate concern would be survival needs, but as soon as there was time for reflection, perhaps I would wonder why I was “born”, how I should behave, and what I ought to accomplish with my life. As I pondered these questions, I discerned two qualitatively different answers.
Do you want to guess what they were?
I will guess but I am sure that my answer will be wrong. But before I do, then please consider the Savior's doctrine that is not imparted to man in general but reserved for the few.
So lets say that once converted then we know the entire plan of salvation. And that is clearly false. We may however know the basic framework of the plan, but not the comprehensive details. And then Satan perverts what little was learned and twists the new student into false doctrines.
And as time goes along the student of salvation learns more along with the false doctrines that were perverted by Satan and an unclear picture of the plan of salvation is held by the student to the point that a similar belief system is accepted as true. And the student fellowships with like kind. This type of learning and belief clearly has the framework of the plan, but lacks the finer details.
These doctrinal beliefs can be easily seen in the LDS, JW, among others. And they believe what they believe along with the errors in their understandings. The same goes for all other Christian beliefs. So what you believe has errors although the framework is correct. And that framework is that Jesus was born upon this earth and paid his life for the salvation of souls. And some denominations have more accurate details associated with the plan than do others.
And the church age is where the saints enjoy the freedom to discern as they wish and they all have salvation in the kingdom of God. But now we are moving beyond the church age into the reign of Jesus Christ upon the earth. This period of time is marked by the Savior's doctrine only. Thus, all the little variations that exist in the church doctrines with no longer exist. We will have the Savior's doctrine only.
The first to have the Savior's doctrine are the 144,000 servants that are called to serve the Savior. They know and will be taught further with respect to his doctrine. If you do not know that John the Apostle is the Davidic King of our time then you will not survive the tribulation.
First of all we were born spiritually first. This was accomplished by accepting Jesus Christ as our God. I do not understand the overall mechanics of this birth but it was before the world was created. That is, in the beginning was the Word, and he is God.
Then the plan of Salvation was given wherein we would be free to choose good or evil. The leaders who were to teach the plan were called. Lucifer was rejected as one of these leaders. So he rebelled to over throw God. And he along with his supporters were cast to the earth. So he is the evil and Jesus is the good and by these two we are to choose how to live our lives. Those who choose Jesus and work to remain faithful have salvation to live with God for ever. Those who do not are consigned to hell and later to be cast out.
So we do not begin with a blank slate. Jesus knew who he was. And John the baptist recognized him from the womb. We have callings that we are sworn to fulfill. And you have done your part. Since you have not been invited to know and understand the next phase then you will go to your glorious reward. However, if you can move forward then please do.
The first qualitative answer is that you accepted the salvation of Jesus Christ for your eternal reward.
The second is that you chose to serve the Savior.
