There is a simple truth that we all know. And that is, love your neighbour as yourself. We can't even do this basic thing so then why are we trying to search out other truths? When we find out the truth what will we do with the info, other than being puffed up with knowledge? Scripture say everything will pass away, even knowledge. But love remain forever. 1Cor 13:8 Love never ends. But as for prophecies, they will come to an end; as for tongues, they will cease; as for knowledge, it will come to an end.
Scripture says, we won't know all the truth at this time. 1Cor 13:9-10 For we know in part, and we prophesy in part. But when that which is perfect is come, then that which is in part shall be done away.
1Cor 13:12 Now we see things imperfectly, like puzzling reflections in a mirror, but then we will see everything with perfect clarity. All that I know now is partial and incomplete, but then I will know everything completely, just as God now knows me completely.
No church or denomination is perfect. They all have truth, as well as wrong information/interpretation.
