(15) See then that ye walk circumspectly, not as fools, but as wise,
(16) Redeeming the time, because the days are evil.
(17) Wherefore be ye not unwise, but understanding what the will of the Lord is.
(18) And be not drunk with wine, wherein is excess; but be filled with the Spirit;
Right after "understanding what the will of the Lord is" comes the exhortation about wine. There are many arguments I've heard about temperance from the Scriptures, however, this seems to be the strongest. We are exhorted to walk wisely and redeem the time, then added to that, understand the will of God and not be drunk with wine. Drunkenness alters the mind. If a Christian is drunk, how can they be sure that they are following God's will? How can they be sure that they are walking wisely?
The Christian should be filled with the Spirit. I believe this exhortation applies to all of the previous exhortations:
- walk circumspectly, as wise -- be filled with the Spirit
- redeem the time -- be filled with the Spirit
- understand the will of the Lord -- be filled with the Spirit
- be not drunk with wine -- be filled with the Spirit
"(9) And I say unto you, Ask, and it shall be given you; seek, and ye shall find; knock, and it shall be opened unto you. (10) For every one that asketh receiveth; and he that seeketh findeth; and to him that knocketh it shall be opened. (11) If a son shall ask bread of any of you that is a father, will he give him a stone? or if he ask a fish, will he for a fish give him a serpent? (12) Or if he shall ask an egg, will he offer him a scorpion? (13) If ye then, being evil, know how to give good gifts unto your children: how much more shall your heavenly Father give the Holy Spirit to them that ask him?" (Luke 11:9-13)
