Specific observations are the most helpful. Simply telling your worship leader, “It didn’t feel like the Holy Spirit” is so vague it’s completely useless. “The second song could have been faster” is more helpful than “Worship really didn’t get off the ground this morning.” It’s better to say, “I thought you shouldn’t have said anything after the third song” than “You talk way too much.” Also, pointing out patterns is better than criticizing every single mistake you noticed.
