It's not so much questioning the holiness of others as much as questioning the direction of the leadership of the church.I agree with Ravenhill that pastors determine the spiritual climate of the churches they preach to. This is not to say that the congregation will ALWAYS be holy if the pastor is holy, but every pastor should realize the responsibility he has to wait upon the Lord in prayer for his flock and to be the example for them.There is more responsibility for those in leadership and God holds them more acocuntable."My brethren, let not many of you become teachers, knowing that we shall receive a stricter judgment." -James 3:1I am mainly concerned with the lack of teaching on holiness because it is so often misunderstood to be preaching legalism.To answer your question, What is holiness: Well, it certainly isn't religion alone, but James also gives us some insight as to what religion can be when it is executed with holiness:"Pure and undefiled religion before God and the Father is this: to visit orphans and widows in their trouble, and to keep oneself unspotted from the world." -James 1:27 (emphasis added)To know what holiness really is, though, let's look at the one attribute of God that the seraphim mention in Isaiah 6: 1 In the year that King Uzziah died, I saw the Lord sitting on a throne, high and lifted up, and the train of His robe filled the temple. 2 Above it stood seraphim; each one had six wings: with two he covered his face, with two he covered his feet, and with two he flew. 3 And one cried to another and said: “Holy, holy, holy is the LORD of hosts; The whole earth is full of His glory!” Here the seraphim aren't singing, "Loving, loving, loving" or "Forgiving, forgiving, forgiving" but "Holy, holy, holy!"God's love is being elevated more than His holiness in today's preaching. Now that's not to belittle God's love - in fact, God's love cannot fully be appreciated outside of a proper understanding of His holiness. If we were see ourselves as God sees us, we ALL would cry with Isaiah: “ Woe is me, for I am undone! Because I am a man of unclean lips, And I dwell in the midst of a people of unclean lips; For my eyes have seen the King, The LORD of hosts.”What is holiness? Holiness is the very nature of God. Love is also the nature of God (1 John 4:16), but even His love is holy. That's why His Son's sacrifice cannot be issued to everyone automatically. Only those who recognize His holiness and their wickedness can even begin to have faith in Christ, for God resists the proud but give grace to the humble (James 4:6, Proverbs 3:34.) God must judge sin for "the soul that sins, it shall die" (Ezek. 18:4.)I could go on describing what holiness is, but this article does a great job:http://www.sounddoctrine.net/Nick/Holiness_God.htmI understand that one can preach holiness all day long but without the moving of God, it won't do any good. I understand that God's grace keeps our striving for holiness from making us go insane or get exhausted - that we must rest in His strength to keep us holy and not in our own. I think grace that's being used as a crutch is not really grace at all. I think it's far overdue for American Christianity to wake up to the hard realities that are around us and to be humbled by how God is calling up a people to Himself in other places.Americans get so disappointed when we don't get the gold at the Olympics, and some national pride is lost when that happens. Well, America sure isn't getting the gold in God's olympics, and there's no remorse in most of our churches over that. We should be striving to win the gold in God's olympics, and holiness is one of the main events.We are made holy through God performing a work of grace in our hearts. We are not made holy by someone yelling at us or pointing out our faults. We are not made holy by any of that, but I can ensure you that holiness will not be instilled in the hearts of Americans by us sitting on our hands. The fervent prayers of the RIGHTEOUS availith much, but who will teach us to pray and to be righteous? Teachers/Pastors are given that responsibility in the local churches. They can only teach it - not force-feed it, but for their hands to be clean of blood, they NEED TO TEACH THEIR CONGREGATION HOW TO PRAY AND BE RIGHTEOUS in order to bring revival!
