Psalm 1:1,2 - Progression of Sin: Walking, Standing, Sitting with Sinners.

Psa.1:1,2; Progression of Sin: Walking, Standing, Sitting with 
Sinners. 

Psa 1:1,2 (KJV)  Blessed is the man that walketh not in the 
counsel of the ungodly, nor standeth in the way of sinners, nor sitteth 
in the seat of the scornful.  But his delight is in the law of the 
LORD; and in his law doth he meditate day and night.  

The verbs "walk," "stand," and "sit" (1:1) describe the 
successive steps of a person's involvement with evil. [New Bible 
Companion] 

Walketh, standeth, sitteth, describe the characteristic steps of 
the wicked which the righteous avoid: accepting the principles of 
the wicked, participating in the practices of outright sinners, and 
finally joining with those who openly mock. Wycliffe Bible Commentary 

"Walk" refers to infrequent ungodliness. "Stand" describes the 
habitual practice of sin. The image "sit in the seat" is of those who 
instruct others in a community's way of life, so that sitting with 
scoffers is hardened commitment to sin's ways. [Victor Bible Reader's 
Companion] 

Walketh, ... standeth, ... sitteth. The three words portray in 
climactic order the successive steps in a life of evil: (1) going in the 
general direction of those who are alien to God, conforming to worldly 
customs; (2) stopping to associate with rebels under the spell of sin, 
dallying with temptation; (3) definitely joining the group of sinners, 
settling down in disregard of light. [SDA Commentary] 

Note the progression of evil from mere association to 
identification to fixation. [Believer's SB] 

The great lesson to be learned from the whole is, sin is 
progressive; one evil propensity or act leads to another. He who acts by bad 
counsel may soon do evil deeds; and he who abandons himself to evil 
doings may end his life in total apostasy from God. "When lust has 
conceived, it brings forth sin; and when sin is finished, it brings forth 
death." (Adam Clarke Commentary) 

His Delight; his will, desire, affection, every motive in his 
heart, and every moving principle in his soul, are on the side of God 
and his truth. He takes up the law of the Lord as the rule of his 
life; he brings all his actions and affections to this holy standard. 
He looketh into the perfect law of liberty, and is not a forgetful 
hearer, but a doer of the word; and is therefore blessed in his deed. He 
not only reads to gain knowledge from the divine oracles, but he 
meditates on what he has read, feeds on it; and thus receiving the sincere 
milk of the word, he grows thereby unto eternal life. This is not an 
occasional study to him; it is his work day and night. Since his heart is 
in it, the employment must be frequent, and the disposition to it 
perpetual. (Adam Clarke Commentary) 

To meditate in God's word, is to discourse with ourselves 
concerning the great things contained in it, with close application of mind 
and fixedness of thought. We must have constant regard to the word 
of God, as the rule of our actions, and the spring of our comforts; 
and have it in our thoughts night and day. For this purpose no time 
is amiss. [Matthew Henry Commentary] 

Day and night-i.e., continually rehearsing God's standards in 
all situations of life. [Jamieson, Fausset, And Brown Commentary] 

Those whom God blesses are not delighted with what pertains to 
sin and the world; they delight in the Word of God. It is love for 
and obedience to the Bible that brings blessing on our lives. See 
Josh. 1:8. The people God blesses not only read the Word daily, but 
they study it, memorize it, and meditate on it during the day and 
night. Their mind is controlled by the Word of God. Because of this, 
they are led by the Spirit and walk in the Spirit. Meditation is to 
the soul what "digestion" is to the body. It means understanding the 
Word, "chewing on it," and applying it to our lives, making it a part 
of the inner person. [Wiersbe's Expository Outlines]
