Well, Psalm 150 is a typical scripture - there's a great variety of instruments there, all engaged in the praise of God. Wouldn't this speak of the assembly? Each member of that one body in the presence of God, each with their own impression to offer up in worship before Him? I'm sure each of these instruments has a particular typical instruction for us, but I have to admit that I don't know all of them! A subject for study, in the power of the Spirit, for sure.
In Luke 15, we have a parable. The Lord told many parables - some about vineyards, others mentioning trading with money, others about great feasts and wedding feasts, one about a sower, one about a merchant seeking beautiful pearls. If we were to take all of these parables literally, we'd be in awful confusion, wouldn't we? Similarly, in this parable, are we to take the robe, the ring and the shoes, literally, when we come into the presence of God? Or do we understand the spiritual bearing, that we're clothed in all the worth of Christ? Are we literally going to take a fattened calf and kill it? Or are we going to see that as another precious figure of the Lord Jesus, as the Sacrifice for sins, of peculiar delight to God in His excellence? Are we going to take the music and dancing literally, or are we going to take up the spiritual bearing, the joy in heaven over one repenting sinner?
Consistency in how we search out the truth is very important, wouldn't you agree? If we get into the habit of picking and choosing (not that I'm suggesting that you're doing this, brother!) scriptures out the midst of spiritual teaching in order to apply them literally to suit our tastes, we end up with inconsistency. We lose far more than we gain by doing that, so we have to be careful of it.
