The Godly - Psalm 1:1-3
If you were to take a study of the entire population of the world and ask them the definition of the word "blessed" chances are you would get an overwhelming majority answer "happy." While it's true that to be blessed is to be content with your place in life and joyful of your surroundings, that isn't the best definition of the word. There are two verses that give us a better insight into the true meaning of this word Psalm 2:12 and Psalm 32:1-2. In Psalm 2:12 the psalmist is attempting to encourage the leaders of government to take heed to the instructions from God (Psalm 2:10-12) and that they must "trust" Him for guidance. Doesn't that show a tremendous relationship between the person and the Creator? So "blessed" has with it the idea of a relationship that results from obedience! But, Psalm 31:1-2 is speaking of salvation, "Blessed is he whose transgression [sin, LMS] is forgiven, whose sin is covered. Blessed is the man to whom the Lord does not impute [count, LMS] iniquity, and in whose spirit there is no deceit." Taking both verses into consideration, along with the definition of the original word (happiness, Strong's) one can easily see that to be blessed is to be joyful based upon obedience to God's commands and salvation from one's sins. That is going to come into play when we study the rest of this section!
Let's think of verse 1 as a conditional statement, because it is. If a person considers his counsel (friendships, relationships, those in whom credence is placed) and does not follow that which would lead him away from godliness he will be blessed. But, as many people have realized, notice the progression! The psalmist speaks about the person that walks, stands and then sits in order to hear unrighteous advice. Isn't that the case in our lives sometimes? We begin a friendship with someone who is not a child of God and therefore not "godly," thereby "walking" with them, and we start to consider their statements, and even teachings, and before we know it we have begun to "sit" and stagnate in their falsehoods! The words of Paul could never be clearer, "Evil company corrupts good habits (1 Corinthians 15:33)"!
If one can read verse two of Psalm 1 and get from it that a person is godly who does not hold the Word of God in high esteem and importance to life, there is something lacking in his reading comprehension skills. How does one combat the false advice of the world? How am I supposed to make sure that my friends who are not members of God's body (cf. Ephesians 1:22-23) do not cause me to lose my way? By the Word of God! There is a big push today for God to speak to mankind and guide them through what could be called nothing other than individual inspiration and revelation and I am convinced it is because we don't realize how important, helpful and divine the Bible and God's commands are! The person wishing to be "blessed" is going to spend time in the word of God (meditate) and be happy (delightful) knowing that God has given him everything that he will ever need, in written form, in order to please the one who created him (2 Timothy 3:16-17, 2 Peter 1:3)! And when a person does that he will be able to stand firm even though the world tells him to do ungodly things, because he will have God's law in his heart and will be profitable to Him (Psalm 1:3).
The Godless - Psalm 1:4-6
When you study what it is to be "godly" (Psalm 1:1-3) and that it is a conditional statement it is almost common sense to understand what it means to be "godless". It is whatever is in exact contradiction to faithfulness, righteousness, godliness and blessedness. It is frailty of being thrown about like dead hulls in the wind (Psalm 1:4) by different doctrines and examples because of the obvious lack of knowledge when it comes to God's word (cf. Ephesians 4:11-16). It's the weakness of a person not prepared to meet their God (Psalm 1:5a, Psalm 1:6, 2 Corinthians 5:9-11). It is the visible contrast seen in a person that is characterized by this compared to a person that is "blessed" (Psalm 1:5b, 1 Peter 2:9).
Godlessness is the plague of the world and yet it can be stopped by simply doing one thing. - Going to God for guidance through His divine words of instruction and dismissing the guidance given by those that have no more religious authority than a bag of grapes. Why would anyone want to go to their neighbor for advice in religious matters when the one that created religion, action based upon one's beliefs (cf. James 1:27), is standing right there just waiting to give it (1 Timothy 2:4)?
