What Is Your Foundation?
Base Texts: Psalm 11:3; Isaiah 28:16; Matthew 7:24–27
Proposition: The stability and faithfulness of a Christian depend entirely on the foundation upon which they build their spiritual life.
Introduction
We live in difficult times—seasons of uncertainty where many Christians find themselves wavering and faltering before the adversities of life. Perhaps you have seen it: believers who were once vibrant now doubting their faith because their foundation was not solid.
If our foundation is built upon men—upon personalities, emotions, or traditions—we will inevitably fall, and our ruin will be great. But if our foundation is set in Christ, nothing and no one can tear us down, even when the fiercest storms beat against our house. Today, we must ask ourselves the most important question of our spiritual journey: On what are we building?
I. The Critical Importance of the Foundation
Text: Psalm 11:3
In any structure, the foundation is the most important part, yet it is the part that is hidden. Everything in the Christian life depends on what is underneath the surface to resist the trials of life.
• The Psalmist’s Query: “If the foundations are destroyed, what can the righteous do?”
• Vulnerability: Without a firm foundation, a believer is left completely exposed to every wind of doctrine and every personal crisis.
• The Urgency: We cannot wait for the storm to arrive before we check our foundation. We must ensure it is solid now.
II. Christ: The Only Unshakeable Foundation
Text: Isaiah 28:16
God has not left us to find our own way. He has established a foundation that is both eternal and firm: Jesus Christ. Isaiah describes this foundation with specific, powerful attributes:
• A Tested Stone: He has already endured the trial and proven His strength.
• A Precious Cornerstone: He is the highest value and the piece that holds everything else in alignment.
• A Sure Foundation: He is well-placed and immovable.
• No Shame: The one who trusts in this foundation will never be put to shame or be moved (2 Timothy 2:19).
Because of Christ, the kingdom we have received is unshakeable (Hebrews 12:28).
III. Two Ways to Build
Text: Matthew 7:24–27
Jesus told a famous story about two types of builders: the Wise and the Foolish.
1. The Wise Man: Built on the Rock.
2. The Foolish Man: Built on the Sand.
The Great Reality: Notice that both builders faced the exact same conditions. Both experienced the rain, the rising rivers, and the wind. The difference in their survival was not the presence of the storm, but the quality of their foundation. The trials of life do not create our foundation; they simply reveal it.
IV. Apostolic Foundation and Building Materials
Texts: Ephesians 2:20; 1 Corinthians 3:11–13
The apostles and prophets laid the groundwork, but they pointed to only one foundation: Jesus Christ. However, Paul adds a warning: how we build on that foundation matters.
• Durable Materials: Gold, silver, and precious stones (deeds of faith, obedience, and truth).
• Perishable Materials: Wood, hay, and straw (human opinions, superficiality, and pride).
• The Test of Fire: Eventually, the "fire" of judgment and trial will test the quality of every person's work. Only that which is built with eternal materials will remain.
V. Two Results Based on Trust
Text: Jeremiah 17:5–8
The Prophet Jeremiah illustrates the difference between trusting in man versus trusting in God:
• The Desert Shrub: The one who trusts in human strength or human opinions is like a bush in the parched desert—weak, dry, and seeing no hope.
• The Tree by the Water: The one who trusts in the Lord is like a tree planted by the water. Its roots go deep; it does not fear the heat, and it never stops bearing fruit.
Many Christians waver because their faith is anchored to a preacher, a family member, or human philosophy. When those people fail (and they will), the person's faith collapses. Our trust must be in the Creator, not the creature.

Conclusion
The question remains: What is the foundation of your spiritual life today?
If your foundation is built on people or temporary circumstances, you are in danger of ruin. But if your foundation is Christ, you will never be put to shame. Do not be a "fluctuating" Christian, tossed about by emotions. Be firm and constant (Hebrews 10:23).
Affirm your faith in Jesus, the Rock of Ages, and you will remain faithful until the very end.
