True. And we are called to be as wise serpents and as harmless as doves. Christians are to be discerning when it comes to judging the character of others and we are to follow the leading of the Holy Spirit. It’s all of that, available to all who have accepted Christ, that protects us from the foolish mistakes that often have tragic consequences.
Oh nobody says you can’t do it wrong. But to pack yourself with a bunch of worldly cynicism is not Christian either.
