God Is Love: The Source, Standard, and Sustainer of True Love

From the series “The Love of God: Revealed, Received, and Radiated”

If we begin anywhere else, we will get everything else wrong.

God’s love is not just one part of who He is. He is not love in balance with other traits, as though His mercy and His justice take turns. Scripture doesn’t leave that option open. It says plainly and without apology: “God is love” (1 John 4:8).

That statement does not mean God overlooks sin. It does not mean He is permissive or pliable. It means that everything He does—whether mercy or judgment, kindness or discipline—flows from a heart that is eternally loving, eternally faithful, and eternally holy.

God is not waiting to become more loving.
He is not learning to be more gracious.
He is not stirred by your behavior into affection.
He is love—unchanging, eternal, and perfect.

The world has taught many of us to view God’s love as uncertain. It offers a version of God who is moody, conditional, and temperamental—always watching and waiting to withdraw from the sinner or the struggling saint. But the love of God is not like the love of men. It does not fluctuate. It cannot be manipulated. It flows from His being—not from your performance.

“If we are faithless, He remains faithful, for He cannot deny Himself.”
— 2 Timothy 2:13

God’s love was not awakened by creation—it is the reason for it. It was not born at the cross—it was revealed there. And it is not sustained by our strength—but by His unchanging character.

To see this love clearly, we must look at the Son.

“God demonstrates His own love toward us, in that while we were yet sinners, Christ died for us.”
— Romans 5:8

The life, death, and resurrection of Jesus Christ reveal the Father’s love—not a sentimental emotion, but a holy, pursuing compassion that lays itself down for the undeserving.

Jesus did not come to change God’s mind about you. He came to show you what had always been true about God’s heart. He came to seek and to save. He came to serve and to give. He came to call, not to coerce. He came to invite the lost into communion with the Father—not by force, but by love.

Christ touched the unclean. He forgave the guilty. He loved His enemies. He died for those who mocked Him. This is not a new picture of God—it is the perfect revelation of the God who has always been.

“He who has seen Me has seen the Father.”
— John 14:9

And yet, Christ’s earthly mission was not the end of this love being poured out—it was the beginning.

“The love of God has been poured out within our hearts through the Holy Spirit who was given to us.”
— Romans 5:5

The same love that formed the world, fulfilled the Law, and conquered death is now within the believer—through the indwelling presence of the Holy Spirit. The Spirit does not offer us a memory of God’s love, but its living presence. He empowers us to walk in love, not as the world defines it, but as Christ demonstrated it.

The fruit of the Spirit begins with love (Galatians 5:22), because love is the root of Kingdom life. It is the proof of discipleship, the fulfillment of the Law, and the mark of divine rebirth.

The early Church knew this well.

They did not follow Christ because He offered them safety or favor in the eyes of the empire. They followed Him because they were convinced of His love—even to death. The Apostolic Fathers wrote about love not as a doctrine to be debated, but a truth to be obeyed.

Clement of Alexandria: “God is good and alone is good… and the good is essentially loving.” (Stromata IV)
Irenaeus of Lyons: “He became what we are, that He might bring us to be even what He is.” (Against Heresies V)
Ignatius of Antioch: “Our God, Jesus Christ… is the expression of the Father’s love, made flesh.” (Letter to the Ephesians)

They knew what the Scriptures taught.
They received what the Spirit gave.
They walked as Christ walked.
And they bore witness to a world that did not know this kind of love.

---

If we are to understand anything else in this series—God’s invitations, His warnings, His commands, and His promises—we must start here:

God is love.
His love is the source of your existence.
His Son is the standard of that love.
His Spirit is the sustainer of it in your life.

Anything less than this is not the gospel.
