It takes a little time, some forgiveness, and swallowing of some pride to admit having to have misjudged someone. After spending time together and each person can see that the other isn't so bad after all, things work out. But how these misguided feelings began is usually fueled by a person or persons who are negative and defensive. It is very very easy to get caught up in this. Especially if your agenda is not anchored in the Lord. Once the smoke is cleared away and the damage rectified, God opens up a new chapter. As wisdom and understanding become more prominent in our lives, better and clearer decisions are made. First we must really think for ourselves. Secondly it doesn't hurt to relax a bit. Think things out. Follow your instinct, that is what God gave it to you for.
Matthew 5:16 In the same way, let your light shine before others, that they may see your good deeds and glorify your Father in heaven.
