The scriptures read are Ezekiel 5-6, Psalm 72 and 1 John 2.
Ezekiel 5. Another enacted parable. As harrowing as the act is (shaving your head and beard with a sword!) the reality is more harrowing. Again this is God's judgment on his people who have turned their back on him.
Ezekiel 6. Ezekiel preaches to the mountains of Israel where the altars and high places of idols were built. Those altars will stand no longer, nor will the people who worshiped there.
Psalm 72. We have a Celtic-flavored version of this psalm tonight.
1 John 2. Jesus is our advocate with God when we sin. The true sign that a person loves God is that he obeys God's commands. The foremost of those commandments is to love. Which means you can't hate a brother of sister in Christ.
BTW, the term antichrist only appears 4 times in the Bible and only in 1st and 2nd John. And notice that John is using it to describe former Christians who have left the Body of Christ and deny Jesus, not a mysterious end-times person as in the Left Behind series or numerous Apocalyptic films. An antichrist is simply someone who denies Christ. It is a descriptive term.
And there's nothing about holing up and fighting. Just maintain a deep connection with God through Jesus, your anointing, which sounds like the Holy Spirit because the anointing teaches a Christian everything he needs to know and that's the Spirit's job.
