Don't know what it is - leadership, preaching, prophecy. Some obvious, some hidden. All have gifts. Bible says the Spirit apportions gifts to the church as he wills, but gives are given to each one. If you are a Christian you have gifts to be used for God and for the church.
Fire can sit and smoulder for ages, give out a little heat.
Still alive, but not making much of a difference to the room. Just a little blow from the bellows, fanning, the smoulders can burst back into flame. We can be like that smouldering log. First of all we have to be alight - can't blaze if you're not alight. First thing - give your life to Jesus Christ and be born into his kingdom.
