God's authority promises eternal life.
What does "His command leads to eternal life" reveal about God's authority and promise?

Setting of the Statement

John 12:49-50 sets the scene. Jesus says: “For I have not spoken on My own; but the Father who sent Me has commanded Me what to say and how to say it. And I know that His command is eternal life”. These are Christ’s last public words before the Upper Room discourse, underscoring their weight.


What “His Command” Means

• Not a suggestion or guideline—“command” (entolē) is an authoritative decree.

• Given by the Father, delivered by the Son, impressed on hearers by the Spirit.

• Summarized in John’s Gospel as believing in the Son (John 6:29) and walking in His word (John 8:51).


God’s Absolute Authority Shines Through

• Source of the command: the Father, “who sent Me.” Divine origin guarantees supreme authority (Isaiah 45:22-23).

• Jesus’ perfect obedience affirms that no higher authority exists (Philippians 2:8-11).

• The command is unchanging; therefore it outlasts all human edicts (Psalm 119:89).


God’s Certain Promise Emerges

• The command carries its own reward: “eternal life.” Promise and precept are inseparable.

• Eternal life is not merely endless existence but knowing God (John 17:3).

• Because the promise is tied to God’s word, it is secure (Titus 1:2).


How Authority and Promise Interlock

1. God’s authority makes the promise dependable—He cannot lie (Numbers 23:19).

2. The promise validates the authority—only One with all power can bestow eternal life (John 10:28).

3. Obedience becomes joyful, not burdensome, because it leads to life (1 John 5:3).


Supporting Scriptures

John 5:24 – “Whoever hears My word and believes Him who sent Me has eternal life.”

Romans 6:23 – “The gift of God is eternal life in Christ Jesus our Lord.”

1 Peter 1:23-25 – The living word that endures forever brings the new birth.


Living in the Light of the Command

• Embrace the word: prioritize Scripture intake, for life flows through it (Deuteronomy 8:3).

• Trust the promise: anchor hope in the finished work of Christ (Hebrews 6:19-20).

• Walk obediently: display God’s authority by gladly doing what He says (James 1:22-25).
