How can i prove an atheist wrong. I have tried many ways but he won't budge. Can i have some good hints!
I need to prove to him that our beloved lord exists!
Generally when people are strongly atheist or strongly Christian it is difficult to argue them out of that position by attacking a single ship out of an entire armada. The armada gives support to the ship you are attacking, and is also called upon to counter-attack you, so it is difficult to win quickly or decisively. You have to realise that winning the battle is almost never about taking out a single ship, even the flagship. It is a battle of attrition. You have to battle long and hard, with the goal not being not so much to sink any one ship, but rather to do enough damage to his fleet that the entire situation changes. So then, I think you are on the right track if you have "tried many ways". Do not think your efforts are having no impact, for many people will not show publically (especially in the middle of an argument/discussion) the doubts or thoughtful contemplations and reconsiderations that is going on in their head.
But conversion is a matter of the heart--a healing of the heart; the war effort is not going to make him convert, it is just going to wear down his defenses. God wants to change our hearts, but we use the head as a defensive fleet preventing that. The goal is to create enough gaps in the defenses to allow grace to slip through. God could force his way through the small rowboats we use by running the intellectual blockade with ironclads, but he prefers to not force himself onto us. Rather, people, using arguments rather than armaments, help others to see where they were wrong (or maybe just potentially wrong). The arguments do no lasting damage, except perhaps to the ego, and it is grace that does the converting.
EDIT--Edited to say... woh, why didn't my verbosity meter go off with that one?
