Exploring the Text

“I, even I, have spoken; yes, I have called him. I will bring him, and he will succeed in his mission.” (Isaiah 48:15)


What “I have called him” Tells Us about God and His Chosen

• God takes the first step

– He speaks before anyone can respond (Romans 8:30; John 15:16).

– The initiative of grace underscores that election rests on God’s will, not human merit.

• The call is personal and specific

– “Him” points to a definite individual—initially Cyrus, ultimately typifying every believer (Isaiah 45:4; John 10:3).

– God knows and names His own (Isaiah 43:1).

• A call with clear purpose

– Cyrus would liberate Israel; believers are freed to proclaim Christ (1 Peter 2:9).

– God never calls without assigning a mission (Ephesians 2:10).

• Divine enabling accompanies the call

– “I will bring him” promises guidance and power (Isaiah 41:10).

– Success is guaranteed because God upholds the chosen (Philippians 1:6).

• Covenant faithfulness is on display

– God’s spoken word binds Him to fulfill it (Numbers 23:19; Psalm 89:34).

– The reliability of His call secures our assurance (Romans 11:29).

• The call is effectual

– What God decrees He accomplishes; resistance cannot thwart Him (Job 42:2; Isaiah 46:10–11).

– Salvation history is the unfolding of His irrevocable summons.


Living Out the Truth

• Rest in God’s initiative—your standing is rooted in His call, not your performance.

• Seek His purpose—ask how your daily tasks advance His mission.

• Depend on His power—He who calls also equips, even when the path looks impossible.

• Stand assured—because His word is unbreakable, your future in Christ is secure.
