There is the Gift of Wisdom for sanctification and the Gift of Word of Wisdom for ministry of service. The first is for us; to second, for another. There are times we are talking to someone, when a thought comes to fore, which we had not previously thought of. It is an insight for the other person. It is a word that will give the other a deeper understanding of a question they are dealing with. Sometimes, we may tend to dismiss the thought. However, as strange as it may seem to say, ask God to give you a peace and then share it with the other person. Let the other person confirm if it is something that helps him/her on not. We are only instruments of God's word. We can be an open vessel or a closed valve. Trust in the Lord. Step out in faith and let God do the rest.
