People hold to things for different reasons. Some people grow up with certain beliefs...and for them that's all there is. But some people have put a lot more time and effort into thinking the ideas through...with God's help of course...to see what is actually being propagated...and over time have moved this way or that away from what was once previously held. And this is is not always to the good...although I think it necessary to "travel" in our minds" to see new places.
In Hebrew the word for "meditate" means to walk in the mind.
Now coupled with the willingness to be critical in one's thinking is God's intervention by the Holy Spirit. So people will divide over how intimacy with God is not only possible but desirable. And they who are opposed to what they have not experienced, do so, with as much conviction as they who have gone further on in the Christian walk. And how is this possible? The bible. So then it is very easy to stumble over the words of the bible...and even Christ Himself. It says so in the bible. In fact, I think that until we have reached the full stature of Christ...we all stumble over one or more aspects of God's will and ways.
I think it is very healthy, dogmatic certainties aside, to investigate the experience of others....AWAY from opinions and dogmatic stances based on a certain reading of the word...in order to find new avenues to the fulfillment of that calling in the Lord.
If we are true seekers then we will easily lay aside our various viewpoints in order to look at those of others. But the dogmatic stuff gets in the way of that...that's when fruitless arguments arise that have no point all. There is nothing edifying in that. So I tend to avoid vain discussions when I see that dogmatism...based on a very human appraisal of what is written in the bible...being presented as having more importance than an open discussion.
So then disagreements can arise...but there is such a thing as the truth. But the truth is that which brings life...not just opinions. So to me, the honesty of a believer should be in regards to speaking things that help others into life....and fortify them against evil and hurtful trends we see...not just in the world...but also in the churches.
And above all dogmatic ideologies taken from reading certain verses in a way that negates the whole counsel of God.
