I use the gift in my private prayer times, and find it an excellent aid to devotion.
I know the concept of a Presbyterian charismatic is a contradiction in terms, but, for me, it works.
There's no need for mass hysteria, or out-of-control nonsense - which is a product of mass hysteria at best, or of great acting skills at worst.
Nor do I even think of contemplating the 'Toronto Blessing' - I have no widh to bark like a dog for Jesus.
However, I take the bit in Romans when Paul say that the Spirit prays for us and in us in groans we cannot fathom as a clue.
Sometimes, whether in stree or in joy, when the words I want to say won't come, I bridge the silence in tongues, and the prayers flow again.
I see nothing dangerous, nor extraordinary in this; nor do I see it as something Christians 'must' or 'must not' have.
The charisma are listed in several places in the Pauline letters - or some of them, because they are simply gifst God uses for His purpose.
It could be healing, or preaching, or admin, or computer skills (I wish....) or whatever - but whatever gift we are given, if we are Christian we are to use it to glorify God, not ourselves.
