Psalm 134 is only 3 verses long, but they are a powerful 3 verses!
1BEHOLD, BLESS (affectionately and gratefully praise) the Lord, all you servants of the Lord, [singers] who by night stand in the house of the Lord.2Lift up your hands in holiness and to the sanctuary and bless the Lord [affectionately and gratefully praise Him]!3The Lord bless you out of Zion, even He Who made heaven and earth.
The instructions to praise the Lord are always, first of all, because He IS worthy of ALL praise and honor and glory! But the reason He tells you and me to praise Him is that praise brings us into close fellowship with Him. It gets our soul (mind, emotions and will) centered on Him and puts us in position to be blessed! Notice what the results of OUR praising Him are in verse 3:
3The Lord bless you out of Zion, even He Who made heaven and earth.
HE will turn around and bless us all over again! What a great God we love and serve! Also, notice that there were those who stood by night to praise the Lord! Anytime and all the time, it is GOOD to praise Him! Someone around the world is praising Him every minute of every day! Just jump in and join the party! AMEN!
Shalom in Him!
