Psalm 128:1 Blessed is every one that feareth the LORD; That walketh in his ways. 2 For thou shalt eat the labour of thine hands: Happy shalt thou be, and it shall be well with thee.
God’s blessing and our happiness is dependent on us realizing that He is God. When we fear Him, that is have an awesome respect and reverence for Him then we will obey Him. When we obey Him we will walk according to what He has taught us in His Word.
He promises that as we honor Him He will see to it that we get to enjoy our work. That we will get out of labor what we put into it rather than seeing it wasted. Things will go well with us and we will be happy.
All that comes from really knowing who God is and respecting and honoring Him and His Word.
