Who are you to judge? How to learn to distinguish between truth, half-truths, and lies

As servants of Christ, we have been seduced by the values of this world and its teaching, according to which people should never judge the beliefs of others, both outside the church and within it.
Many are convinced that we have no right to judge anyone's lifestyle and faith. We have lost the ability to judge this world because we have lost the ability to judge ourselves.
“Who are you to judge?” is a book dedicated to such a quality of a person as discernment, the ability to distinguish between lies and truth or, better yet, lies from half-truths. Our responsibility as church members is to distinguish biblical Christianity from false spirituality and the values of today's world.
