The Holy Spirit is like a teacher, the Bible is like the text book, and the Spiritual gifts are like the fun games, toys, demonstrations the teacher chooses to explain the textbooks.
If someone's a new believer, he's like a little child. For a child to learn by himself through textbooks, it can be very hard and boring. But if the teacher chooses some toys and skillfully demonstrate it, the learning can be fun and exciting. They're all for the same purpose, to help us grow into maturity. If your a more mature Christian, an older student, you probably don't need that much demonstration and fun things in the class, you can just "eat" your textbooks, but for the younger ones, the toys etc. are "gifts",they're presents for us to enjoy and have fun with.
For example, in a meeting someone uses his prophetic gift to speak into another person's(let's just name him Alex) life, like"Alex, your having a hard time struggling with dadada issues, I want you to know that I'm your father, put your trust in Me, don't worry and I'll lead you out..." These words speaks straight into Alex's heart at that moment. Well, he can find the same truth, words in the Bible, but this way he'll really get it. Another example, Martha's having cancer. She comes to a meeting and someone with a healing gift comes and pray for her and she got instantly healed. (demonstration of a truth) Now she can find all the healing verses in the Bible, but this way it will be a vivid demonstration to her and she'll learn that lesson much easier.
All these spiritual gifts are just like presents for us to enjoy while learning and growing. All kids love present, don't they? And clever parents and teachers use toys and fun things to teach kids rather than the old traditional type of method,"Just study the textbook!"
So, being a Christian, would you rather grow up(or helping your kids grow up) having lots of fun while learning or just sit still in the classroom all day long only reading the textbooks?
I wouldn't say no to the pressies. I love them!
