“Hear, O Lord, my righteous plea;
listen to my cry.
Give ear to my prayer -
it does not rise from deceitful lips
May my vindication come from you:
may your eyes see what is right.
Though you probe my heart and examine me at night,
though you test me, you will find nothing;
I have resolved that my mouth will not sin.
As for the deeds of men -
by the word of your lips
I have kept myself
from the ways of the violent.
My steps have held to your paths;
my feet have not slipped.
Psalm 17:1-5
Notice how many times in just these five verses the psalmist makes reference to what comes out of his mouth? “My righteous plea†– “It does not rise from deceitful lips†– “My mouth will not sin†For the psalmist, purity in speech and word are equal to having a pure heart (vs 3) and walking in obedience (vs 5). James, in his epistle, echos that sentiment when he wrote, “If anyone is never at fault in what he says, he is a perfect man, able to keep his whole body in check†(James 3:2). For many of us, the first step to walking in holiness before God is to tame our tongues.
But the psalmist does not stop by declaring that the words of his lips have been righteous. He also declares the very source of his obedience. “By the words of your lips, I have kept myself from the ways of the violent†(vs 4). It is by the Word of God that the psalmist guards his own words. That is just as true for us today as it was for the psalmist. Yet we have experienced the Word of God in a more powerful way than the psalmist ever imagined. We have the Word of God become flesh in Jesus Christ. “In the past God spoke to our forefathers through the prophets at many times and in various ways, but in these last days he has spoken to us by his Son†(Heb. 1:1-2). Our lips, our actions and our hearts will be declared righteous as we hold to the Word of God, Jesus Christ.
