@ash Sure thing! Yes, it is alluring to try to attempt to convince someone to believe, but the most we can do is lay out the evidence in each area of life - origin, meaning, morality and destiny - and the truth of Christ - and allow the Holy Spirit to do His good work in their heart.
In “Christianity for Modern Pagans” Peter Kreeft examines Pascal’s work. One argument Pascal makes is that God gives exactly enough light for the righteous to find Him and for the wicked to reject Him.
"He gives exactly the right amount of light. If He gave less, even the righteous would be unable to find Him, and their will would be thwarted. If He gave more, even the wicked would find Him, against their will. Thus He respects and fulfills the will of all.
If He gave more light, the righteous would not learn humility, for they would know too much. If He gave less light, the wicked would not be responsible for their wickedness, for they would know too little."
I like this argument and think there is a lot of truth in it. We should give a reason for the hope that is in us, but the rest is between the individual and God.
