What does 1 John 3:16 mean?
What is the meaning of 1 John 3:16?

By this we know what love is

“By this we know what love is:” (1 John 3:16a)

• Love is not guessed at; it is revealed with certainty. Our standard is God’s own demonstration, not cultural opinion (cf. 1 John 4:9-10; Romans 5:8).

• The phrase “we know” reminds believers that the knowledge of love is objective and available to every Christian through Scripture’s clear testimony (cf. John 13:35).

• Love, therefore, is measurable by God’s action, removing every excuse for selfish definitions.


Jesus laid down His life for us

“Jesus laid down His life for us,” (1 John 3:16b)

• The Lord’s voluntary sacrifice defines love’s highest expression (cf. John 10:11, 18).

• “For us” underscores substitution—He took our place under divine justice (cf. Isaiah 53:5; 2 Corinthians 5:21).

• The Cross is not merely an inspiring story; it is the literal, historical act by which sins are atoned (cf. Hebrews 9:14; Philippians 2:8).

• Because the Gospel is factual and finished, our assurance is unshakable.


and we ought to lay down our lives for our brothers

“and we ought to lay down our lives for our brothers.” (1 John 3:16c)

• “Ought” moves the verse from information to obligation; the believer’s life must mirror the Savior’s (cf. John 15:12-13).

• Practical applications:

– Daily self-denial—putting another’s need ahead of personal comfort (Luke 9:23; Philippians 2:3-4).

– Bearing burdens—investing time, resources, and energy to relieve fellow believers (Galatians 6:2; James 2:15-16).

– Persevering loyalty—standing with brothers and sisters even when costly (Romans 12:1; 1 Corinthians 13:4-7).

• While physical martyrdom may be required for some, the ordinary call is continual, tangible sacrifice that reflects Christ’s heart.


summary

Love is clearly defined by God, displayed in the literal, historical sacrifice of Jesus, and demanded of every follower. Knowing this, believers actively choose daily, costly service for one another, confident that in doing so they walk in the very footsteps of their Savior.
