Does it really matter if atheists hold their view/opinion that God does not exist?
Is it not their own choice to do so?
Can a theist truly "convert" the non-believers?
Or is it in the very rare case when an atheist begin to change into a believer, their own change in action, words and thoughts that lead them to some form of belief?
To the world I think it matters because we are what we believe. You know the saying “what you eat today walks and talks tomorrow”? I think that applies equally to thought, belief and mindset.
I believe we are not alone and that we are a progressive species. That is, our civilisations grow and develop throughout the ages.
And in order to assist us in that growth and development God sends us Prophets with teachings and a plan for that age which will help us make a smooth transition to the next stage in our development.
Now an atheist would ignore that plan and go his own way. As would every religionist ignore the latest Messenger. The result being, a society in chaos and confusion without the necessary wisdom or guidance to help solve its problems.
So humanity’s progress towards a golden age of peace and a spiritual world civilisation gets put on hold because people choose to ignore the guidance given to mankind for this age by God. You can see the result. Mental illnesses abound, suicide, drug addiction, domestic violence, homicide, wars, a huge gap between the rich and poor.
The failure to trust in God and implement His Plans can only invite disaster. People have become too proud to admit they got it wrong and it’s time to try God’s ways for this time.
So who will be responsible if humanity suffers another catastrophe? It will be us who chose to ignore God’s counsels for this age. But there is no force. We are free to choose however there is a vast difference between man’s wisdom and God’s.
On one side are all the calamities and crises and on the other a golden age and a world spiritual civilisation. The choice is ours.
