Other scriptures on ingratitude to God?
Which other scriptures warn about the dangers of ingratitude towards God?

Setting the Scene

Gratitude is not a polite extra; it is the proper response of a creature to the Creator. Scripture consistently links ingratitude with spiritual darkness, decay, and judgment. Romans 1:21 highlights the spiral that begins when people “neither glorified Him as God nor gave thanks to Him.” Throughout the Bible, the Lord warns that forgetting His goodness leads to ruin.


Romans 1:21—A Foundational Warning

“For although they knew God, they neither glorified Him as God nor gave thanks to Him, but they became futile in their thinking and their foolish hearts were darkened.”

• Failure to thank God is not a minor oversight; it opens the door to futile thinking and a darkened heart.

• The verse anchors every other passage that cautions against a thankless life.


Echoes of the Warning in the Old Testament

Deuteronomy 8:10-14, 17-19

• “Be careful not to forget the LORD your God… Otherwise… your heart will become proud and you will forget the LORD your God… If you ever forget the LORD your God… you will surely perish.”

• Prosperity can dull gratitude; the consequence is destruction.

Deuteronomy 28:47-48

• “Because you did not serve the LORD your God with joy and gladness of heart in all your abundance, you will serve the enemies the LORD will send against you…”

• Joyless service equals ingratitude; bondage follows.

Psalm 106:13, 21

• “They soon forgot His works… They forgot God their Savior…”

• Forgetfulness breeds rebellion and judgment (read the whole psalm for the tragic cycle).

Psalm 50:22

• “Now consider this, you who forget God, lest I tear you to pieces, with none to rescue you.”

• Stark language underscores the danger of neglecting thankful remembrance.

Numbers 14:27-29; 1 Corinthians 10:10 link

• Israel grumbled; the wilderness generation died there. Paul says, “Do not complain… and were killed by the destroying angel.” (1 Colossians 10:10)

2 Chronicles 32:25

• “But Hezekiah did not repay the favor shown him, for his heart became proud; therefore wrath came upon him…”

• Neglecting gratitude invites wrath, even for formerly faithful people.

Malachi 2:1-2

• “If you do not take it to heart to honor My name… I will curse your blessings.”

• The priests’ ingratitude turned their blessings into curses.


New Testament Alerts and Illustrations

2 Timothy 3:1-5

• “In the last days terrible times will come. For men will be… ungrateful…”

• Thanklessness is a hallmark of end-times depravity.

Luke 17:17-18

• “Were not all ten cleansed? Where then are the other nine? Was no one found to return and give glory to God except this foreigner?”

• Jesus publicly notes ingratitude; only one leper’s faith is celebrated.

Hebrews 12:28-29

• “Since we are receiving an unshakable kingdom, let us be filled with gratitude, and so worship God acceptably… For our God is a consuming fire.”

• Gratitude is the acceptable posture; refusal risks encountering God’s consuming fire.

Philippians 2:14

• “Do everything without complaining or arguing.”

• The antidote to grumbling is thankful obedience.

1 Thessalonians 5:18

• “Give thanks in every circumstance, for this is God’s will for you in Christ Jesus.”

• God’s revealed will explicitly opposes ingratitude.


The Heart Behind Ingratitude

• Pride—crediting ourselves for God’s gifts (Deuteronomy 8:17).

• Forgetfulness—allowing blessings to dull memory of the Benefactor (Psalm 106:13).

• Idolatry—turning to other “gods” when thanksgiving fades (Romans 1:21-23).

• Complaining—verbalized ingratitude that spreads unbelief (Numbers 14:27).


Putting It All Together

Scripture’s chorus is clear: thanksgiving guards the heart, honors God, and steadies the mind. Ingratitude invites pride, darkness, and even national ruin. The safest, brightest path is to “Enter His gates with thanksgiving” (Psalm 100:4)—and never leave that posture.

How can we guard against having 'foolish hearts' as mentioned in Romans 1:21?
