Dear Elsa,
Prayer before responding can be of great help when responding to certain posts, if not it can leave room for the Enemy to cause division amongst the body of Christ and its members. An that is usually the cause of dissensions on many forums, unity and agreement is what every Christian on this forum should seek and not division. If one is to be corrected, let him/her be corrected in the spirit of humility and not arrogance like some do.
Romans 8:26 - Likewise the Spirit also helpeth our infirmities: for we know not what we should pray for as we ought: but the Spirit itself maketh intercession for us with groanings which cannot be uttered.
God Bless!
