Link John 16:31 to Thomas's doubt.
Connect John 16:31 with another instance of doubt in the Gospels.

Setting the Moment in the Upper Room

John 16:31: “Do you finally believe?”

• Jesus has just revealed stunning truths about His return to the Father and the coming of the Spirit (John 16:5-15).

• The disciples respond, “Now You are speaking plainly… we believe You came from God” (16:29-30).

• Jesus immediately tests that claim—He knows their professed certainty will soon collide with fear and scattering (16:32).


An Earlier Storm of Doubt on the Lake

Matthew 14:31: “Immediately Jesus reached out His hand and caught him. ‘You of little faith,’ He said, ‘why did you doubt?’”

• Peter stepped out of the boat in bold confidence, literally walking on water toward Jesus (14:28-29).

• The wind distracted him; his gaze shifted from Christ to the waves, and he began to sink (14:30).

• Jesus rescued him and pinpointed the issue: not the storm, but Peter’s divided focus and faltering trust.


Connecting the Two Scenes

• Both episodes follow affirmations of faith—words in the Upper Room, footsteps on the water.

• Jesus’ challenge (“Do you finally believe?” / “Why did you doubt?”) exposes the thin line between bold confession and shaky conviction.

• In each case, the disciples need more than momentary confidence; they need Spirit-empowered perseverance (John 14:16-17; Acts 2:4).

• The Lord does not abandon them: He rescues Peter physically and promises the Spirit to fortify all of them spiritually.


Key Lessons for Every Disciple

• Genuine faith is proven in pressure. Assurance voiced in calm must stand when storms or persecution arise (1 Peter 1:6-7).

• Doubt often enters when focus shifts from Christ’s sufficiency to surrounding circumstances (Hebrews 12:2-3).

• Jesus confronts doubt, yet He also compassionately upholds those who falter (Jude 24).


Living It Out

• Keep eyes “fixed on Jesus, the pioneer and perfecter of faith” (Hebrews 12:2).

• Anchor confidence in His unchanging Word, not in fluctuating feelings or external stability (Psalm 119:105; Matthew 24:35).

• Rely on the Holy Spirit—the promised Helper—to turn confessed belief into steadfast endurance (John 14:26; Romans 8:11).
