Acts 14:2 But the unbelieving Jews stirred up the Gentiles and poisoned their minds against the brethren.
Once doubt sets in to a group of people they either fall apart or they start sharing their doubt and breaking down faith where it used to be.
We have been warned against a little evil getting into a group many times in the bible, and yet we think we are stronger than the doubt.
Don’t try to fight doubt by yourself or by your own words, always use what God has given us because he knows about this doubt already.
Use God’s words wisely and always.
