"... not forsaking our own assembling together, as is the habit of some..."
What an interesting peek into first-century church attendance (!)... then, as now, the flesh cooperated with the enemy to oppose gathering regularly with other believers for worship.
And the flesh is amazingly adroit when it comes to excuses & reasons for staying away---
"I don't get anything out of the sermon." "All the people down there at the church are hypocrites, anyway." "Sunday is the one day I can get everything done I couldn't do all week." "All that preacher talks about is money." "I can worship better in the privacy of my own home, with the televised service." "They don't miss me, nohow." "After what they did, I wouldn't go back there if they begged me!" "I have my radio preachers." "It's just a country club over there." "It's too big." "It's too small." "It's too far." And a multitude more beside these...
These expressions of the flesh, with its selfishness, wounded pride, laziness, and arrogance, work hand-in-glove with the enemy of our soul in his hatred of the assembled saints known as the church.
Why would he bring to bear such incessant pressure against the body of Christ, both from without and from within? Better than we, he knows the spiritual impact in the unseen realm that is unleashed when God's people meet in worship of their sovereign King. Gauging by how much opposition our enemy puts forth, we can be assured the regularly-assembled church does some rather serious damage to his kingdom, and he is not amused.
Is there spiritual warfare going on every time the body of Christ gathers in His Name for corporate worship? Absolutely. Indeed, the enemy is already at work before folks ever leave their homes, seeking to dissuade them from even coming to God's house of worship, lest his kingdom of lost souls sustain even more damage. Were we to catch but a glimpse of that realm on a morning when believers are preparing to gather, how much more diligent we would be to put on the whole armor of God in prayer, with a keener awareness of what's at stake in the heavenlies when the Word goes forth from the pulpit! May the living God of all that is, grant a genuine awakening among His people, restoring a zeal for gathering in His Name faithfully, regularly, joyfully, encouraging one another as the day of His return draws near.
