In these days everyone has their own "truth" which to them is an absolute but in reality it is obsolete when held up against God's Word. We must use wisdom in these last days and not refuse it. You can be bold, wise, firm and still walk in the fruit of the Spirit. To be kind doesn't meant to be timid and nonconfrontational. Let the Holy Spirit lead you and stand up for the truth of the Bible. It is still ahead of our time. Anyone that refuses it is a fool according to Proverbs 1.
