Worship is the act by which we are joined to the Lord as one spirit. That is why worship is the highest activity of human beings. Again, when we are joined to the Lord in worship, we begin to bring forth (or birth) the things that God wants brought forth.
Worship is not an appendix to the Christian life; it is not a little addition to services. It is the culmination. It is the confirmation. Once more, if I may put it in this way without offending anyone, it is the consummation of our marriage to the Lord. We are united with Him as one spirit, and when we have that marriage union, it is always for the sake of procreation. That is when spiritual fruit comes out of our lives.
You need to know the identity of the husband with whom you are united. Paul wrote in Galatians 5:19–21, “Now the deeds of the flesh are evident, which are: immorality, impurity, sensuality, idolatry, sorcery, enmities, strife, jealousy, outbursts of anger, disputes, dissensions, factions, envying, drunkenness, carousing, and things like these” (nasb). The deeds of the flesh are all too evident. You can tell people that you are spiritual, but if you are truly fleshly, it will show. Let me ask you this: Do you want your children to act like what is described in the passage from Galatians? Because that is what the flesh brings forth. You cannot find one good thing in that entire list. The flesh cannot produce anything acceptable to God. It is corrupt. Jesus said that a corrupt tree cannot bring forth good fruit. (See Matthew 7:18.) It is impossible.
