What does it mean to be on the Lord's side?

"When my enemies turn back, they stumble and perish before your presence. For you have maintained my just cause; you have sat on the throne, giving righteous judgment. You have rebuked the nations; you have made the wicked perish; you have blotted out their name forever and ever. The enemy came to an end in everlasting ruins; their cities you rooted out; the very memory of them has perished." Psalm 9:3-6

The Psalmist here is speaking about some of God's "wonderful deeds" which led to the protection of His people. In a larger sense, God may have also been pointing to the judgment that will take place in the future. Regardless, it is pretty clear whose side we should desire to be on. We should worry less about whether or not God is on our side and be concerned about where we stand. If we are on God's side, He is most definitely on our side. What does it mean to be on God's side? For me, it means learning more about Him each day so that that I can better serve Him. To serve Him, I should be bearing fruit through my witness to lost people and through my encouragement to saved people. I should be living my life in such a way as to be bringing glory to God each day. I should be living for His glory alone. Soli Deo Gloria - "glory to God alone." If I do everything each day with the glory of God in mind, then won't I be rightly serving Him?

Who is on the Lord's Side
by Frances Havergal

Who is on the Lord’s side? Who will serve the King?
Who will be His helpers, other lives to bring?
Who will leave the world’s side? Who will face the foe?
Who is on the Lord’s side? Who for Him will go?
By Thy call of mercy, by Thy grace divine,
We are on the Lord’s side—Savior, we are Thine!

Not for weight of glory, nor for crown and palm,
Enter we the army, raise the warrior psalm;
But for love that claimeth lives for whom He died:
He whom Jesus nameth must be on His side.
By Thy love constraining, by Thy grace divine,
We are on the Lord’s side—Savior, we are Thine!

Jesus, Thou hast bought us, not with gold or gem,
But with Thine own life blood, for Thy diadem;
With Thy blessing filling each who comes to Thee,
Thou hast made us willing, Thou hast made us free.
By Thy grand redemption, by Thy grace divine,
We are on the Lord’s side—Savior, we are Thine!

Fierce may be the conflict, strong may be the foe,
But the King’s own army none can overthrow;
’Round His standard ranging, victory is secure,
For His truth unchanging makes the triumph sure.
Joyfully enlisting, by Thy grace divine,
We are on the Lord’s side—Savior, we are Thine!

Chosen to be soldiers, in an alien land,
Chosen, called, and faithful, for our Captain’s band,
In the service royal, let us not grow cold;
Let us be right loyal, noble, true and bold.
Master, Thou wilt keep us, by Thy grace divine,
Always on the Lord’s side—Savior, always Thine!
