Psalm 118 begins this way:

Give thanks to the LORD, for He is good;
For His lovingkindness is everlasting.
Oh let Israel say,
“His lovingkindness is everlasting.”
Oh let the house of Aaron say,
“His lovingkindness is everlasting.”
Oh let those who fear the LORD say,
“His lovingkindness is everlasting.” (vv. 1-4)

And it ends this way:

You are my God, and I give thanks to You;
You are my God, I extol You.
Give thanks to the LORD, for He is good;
For His lovingkindness is everlasting. (vv. 28-29)

Do you think the Psalmist is trying to emphasize something?  Of course he is.  He is reminding people who are prone to forget the lovingkindness of God (in the NT, we would probably call this “grace”) that God is persistent in His love and care for His people.

There are three particular emphases with this statement, “His lovingkindness is everlasting.”  First, it means the obvious — the gracious care that God gives to His people is unending.  It extends to the end of time and beyond that into eternity.  There is no limit or end to His kindness to His own.

And since His lovingkindness is everlasting that also means, secondly, that it is uninterrupted.  Were the loyal love of God interrupted for even the briefest of moments, then those who are in heaven would instantly be consigned to hell and all men on earth would immediately receive the same judgment.  Yet His loyalty cannot be interrupted.  It cannot diminish one fraction of a percentage point for even a flickering moment.  He is loyal.  He is faithful to Himself.  And He can never be anything except loyal and faithful to His own.  Those who are His have received a promise that is eternal and uninterruptable.

Thirdly, the loyal love of God is not something that begins after the end of time, but it has already begun.  God has bestowed His love on His children — first Israel, and now the redeemed church of Christ — and that love is being experienced even now.  It may be difficult for the believer in God and Christ to believe that his troubling circumstances have passed through the loving hands of God.  But they have.  And that is the point of the psalmist in the middle section of the psalm.  When distressed by others, God’s lovingkindness is a refuge (vv. 5-9).  When surrounded by ungodliness in the world and persecution, God’s grace is still a strong help (vv. 10-14).  Death is no source of fear for the believer (vv. 15-18).  In all circumstances, we can give thanks and rejoice because the Lord is both good and sovereign (vv. 19-27).

His lovingkindness is everlasting.
