Introduction (2 minutes)

Most of us have lived long enough to know something about wilderness seasons.

Illness, Loss, Family struggles and Uncertain times

Yet if we are honest, even after seeing God work in our lives, we sometimes complain when the next challenge comes.

That is exactly what happened to Israel.

In Exodus 17, the people who had seen:

The Red Sea open

Manna fall from heaven

God guide them by cloud by day and fire by night now complain because they are thirsty.

Their complaint reveals something deeper: They have forgotten what God has already done.

Complaining Begins When We Forget God’s Past Faithfulness (4 minutes)

Exodus 17 The people say:

"Why did you bring us out of Egypt to kill us?"

They speak as if God had never helped them before.

But they had already seen AND experience

Deliverance from slavery

Protection from Pharaoh

Daily provision of manna

Yet one new problem caused them to forget everything God had done.

Psalms 95:8: "Do not harden your hearts as at Meribah."

You have seen God:

Carry you through illness

Provide for your family

Sustain you through grief

But even seasoned believers can fall into the trap of spiritual amnesia.

2. Complaining Tests God Instead of Trusting Him (4 minutes)

Exodus 17:2 says: The people demanded:

"Give us water to drink." They were not praying they were accusing.

They asked in verse 7: "Is the Lord among us or not?"

That is the real issue behind complaining.

Complaining often says:

"God, I am not sure you are really taking care of me."

The New Testament echoes this warning.

In First Epistle to the Corinthians 10:10 Paul writes:

"Do not grumble, as some of them did and were destroyed."

And in Philippians 2:14–15: "Do everything without grumbling or arguing."

Why?

Because complaining damages our witness and erodes our trust in God.

3. Remembering God Changes Complaining into Gratitude (4 minutes)

God gave the church a powerful gift to fight forgetfulness.

Jesus said in Gospel of John 14:26:

"The Holy Spirit will remind you of everything I have said to you."

The Spirit helps believers remember God’s faithfulness.

For many older Christians, faith is strengthened by memory.

You remember:

prayers God answered years ago

the day you came to Christ

the ways God sustained your family

Those memories become anchors of faith.

Gratitude grows when we intentionally remember.

4. Lent Calls Us to Replace Complaining with Trust (3 minutes)

Lent is a season of spiritual reflection.

It asks us to examine our hearts.

Sometimes we discover that our complaining is not really about circumstances it is about forgetting God’s goodness.

The Israelites asked:

"Is the Lord among us or not?"

The cross answers that question forever.

In Christ we know: God is with us.

He has already given us His greatest gift.

If God gave His Son for us, surely He will not abandon us in our wilderness.

Conclusion (2 minutes)

Complaining reveals a forgetful heart.

But remembering reveals a faithful God.

So when the wilderness comes and it will ask yourself:

What has God already done for me?

Remember the Red Seas He has already parted in your life.

And when we remember, complaining gives way to gratitude, trust, and peace.
