These things I speak of are not things that are to be proven in Scripture.
Partly true. what I have come to see now is that I think all we will ever know in this life is contained in scripture.
The issue you speak of whether you agree with me or not is that I cannot just open the bible show you a scripture and prove it to you, but it is there.
People misunderstand spiritual discernment. People talk about it, people use it to to slight another person in a argument or discussion by pointing out that since someone is not understanding or believing what they say, they say it must be spiritually discerned. So of course, someone who doesn't believe them must not be spiritually discerning. Well, I believe spiritual discernment is a real thing, but if its real in our lives, then we do not need to use it in the manner of trying to convince someone of something that they cannot just choose to have.
If spiritual discernment is a choice from our ability, then it would not be a problem to teach and instruct someone how to do it. No one can, they only try in the manner you spoke of.
I'm just as accountable for doing all of the above, but I am at a point now where I have nothing to prove because I simply have faith that my walk is the walk that God intends for me. I must move on and if someone needs me to explain what it is i am doing then I must simply continue to walk in the faith that God will show them one day what it is they should do.
The waiting part is not a solution, it is only a result of faith. It is impossible to teach someone else how to have faith because we are not the providers of it.
I run the race, even if physically I see no evidence that it is worth my time. That is the hardest thing to ever do. But, as much as I want to be the one running, there is no running "till" Christ has chosen me to be in it.
In short, people will believe in the gospel of ultimate reconciliation when God has it planned for them to do so. People will walk in the spirit when they move from being called to being chosen.
In the meantime, the only real meat we can physically manifest to show anyone else is to DO.
Do what? Someone will ask. Tell others of the hope that we know and live a genuine life that shows what we believe, rather than going round and round hoping we simply convince ourself.
