"Blessed is the man
Who walks not in the counsel of the ungodly, Nor stands in the path of sinners, Nor sits in the seat of the scornful; But his delight is in the law of the LORD, And in His law he meditates day and night." Psalm 1:1-2

Blessed here in the Greek is MAKARIOS meaning: supremely blest; fortunate, well off -- blessed, happy. This is the word used in the following:

Psalm 1:1 in The Amplified Bible reads,
"BLESSED (HAPPY, fortunate, prosperous, and enviable) is the man who walks and lives not in the counsel of the ungodly..."

It is the word used in Matthew 5:3,4,5,6,7,9,10,11 and in The Amplified Bible reads, "Blessed (happy, to be envied, and spiritually prosperous--with life-joy and satisfaction in God's favor and salvation, regardless of their outward conditions)..."

This word is also in Revelation 1:3 (as well as six other verses), "Blessed (happy, to be envied) is the man who reads aloud [in the assemblies] the word of this prophecy; and blessed (happy, to be envied) are those who hear [it read] and keep themselves true to the things which are written in it..." The Amplified Bible

It seems that people are always seeking happiness in this world. They chase after things that will make them happy. "If only I had this..." "If only he/she would..." "If only I could do such and such..." If only, If only If only! Though some, even many, of these wants and desires are accomplished, it is never enough and soon the demand is for more. But happiness does not depend on things or circumstances! As we have seen in these few Scripture verses (and please read them in their fullness), happiness is the by-product of something else.

Psalm 1:1 is stated in the negative, the blessed, happy one walks not, nor stands; nor sits with the ungodly.
"But his delight is in the law of the LORD, (and not only does he delight) And in His law he meditates day and night." Vs. 2 (My parenthesis)

To meditate is more that merely reading, but it is to ponder and study.

The apostle Paul tells us in 2 Timothy,
"Every Scripture is God breathed (given by His inspiration) and profitable for instruction, for reproof and conviction of sin, for correction of error and discipline in obedience, [and] for training in righteousness (in holy living, in conformity to God's will in thought, purpose, and action.)
2 Timothy 3:16 The Amplified Bible.

Psalm 1:3 tells us what this man will be like?
"He shall be like a tree
Planted by the rivers of water,
That brings forth its fruit in its season, Whose leaf also shall not wither; And whatever he does shall prosper."

"Oh, taste and see that the Lord is good; Blessed (happy) is the man who trusts in Him." Psalm 34:8

Thank you Lord for Your saving grace, Your grace that justified and Your grace that is teaching us to live righteously! As we live in trust and obedience to You, happiness is ours no matter what the conditions or circumstances. We love, adore and gratefully thank You! Amen
