Trinitarian Christians claim to be monotheists thought their subgod Jesus has lesser qualities in common than many polytheists their main god and subgods. God may perhaps not to be found in perceivable attributes but when looking around and reading the Bible like the words are written in that book then it should not be so difficult and not so confusing to come and see Who God really is.
Though many things may be very difficult to proof that does not mean that they would not exist. Also feelings and experiences are difficult to proof, though the results of a God-Being in our life is something what many feel. One thing is for sure: "If God does not exist, then everything is permitted". In the transcendent reality we can not see nor fully understand God but somehow looking around us and listening to our inner feeling each person should be able to come to recognise the Supreme Power and to understand that reality is shaped by a Power beyond us.
When men let their faith and confidence in the credibility of the Word of God get away from them, there is danger of lowering their ethical standard. A tottering faith in the Bible narratives shall bring morality to be unstable and to stagger also. When there is a rejection of the integrity of the Old Testament narratives there shall be no vibration to come to see the truth of this life and the person shall move or sway unsteadily or unsure in this materialist world were more and more people are moving away from God and are having their egoism being the base of their life disturbing their relationships, making them unstable.
