Acts 14:2 But the unbelieving Jews stirred up the Gentiles, and made their minds evil affected against the brethren.
Unbelievers are not simply willing to not believe. They must make sure and stir everyone up not to believe and to think evil thoughts about those that love Jesus. There is an antagonism against Jesus and the things of God. Christianity is a love/hate religion.
It is not simply that people refuse to believe in Christ. They must attack Him. They have freedom of religion. They can believe or not but that is not enough. They must fight against Jesus.
It is similar to Saul kicking against the pricks. It is almost mandatory for the atheist not only to not believe but to convince others not to believe.
It is like not believing is not enough. They are as evangelistic as any Christian in their attack on the faith of others.
So nothing new happening today. It happened all the way back in the book of Acts. Do not be surprised when people work at destroying your faith. It is what unbelievers do!
