Trusting God's knowledge of our lives?
How can we trust God's knowledge of our lives, as Psalm 37:18 suggests?

Opening the Text

Psalm 37:18: “The LORD knows the days of the upright, and their inheritance will last forever.”


God’s All-Knowing Character

• God’s knowledge is total and immediate—nothing about His creation escapes Him (Psalm 147:5; Hebrews 4:13).

• His omniscience is not abstract; He knows specific details about individuals (Psalm 139:1-4).

• Because He is truth (John 14:6) and cannot lie (Numbers 23:19), His knowledge is perfectly reliable.


What It Means That He “Knows the Days”

• “Knows” indicates more than awareness; it reflects personal, covenantal involvement.

• “The days” covers every moment from birth to eternity—past, present, future (Job 14:5).

• For the “upright,” this knowledge is paired with purpose: He actively ordains each day for their good (Romans 8:28).


Reasons We Can Trust His Knowledge of Us

1. Proven Faithfulness in Scripture

• Joseph’s life: God numbered each twist of betrayal and promotion (Genesis 50:20).

• Israel in the wilderness: daily manna showed He knew their exact need (Exodus 16:4-5).

2. Christ’s Personal Assurance

• “Even the hairs of your head are all numbered” (Matthew 10:30).

• His crucifixion was foreknown and planned “before the foundation of the world” (1 Peter 1:20).

3. Unchanging Nature

• The God who perfectly knew saints of old knows believers today (Malachi 3:6; James 1:17).

4. Eternal Inheritance Guaranteed

• Because He holds our future, the promised inheritance “will last forever” (Psalm 37:18b; 1 Peter 1:3-4).


Living in Light of His Perfect Knowledge

• Rest: Anxiety loses power when every day is already under His watch (Philippians 4:6-7).

• Obedience: Each act of faithfulness is seen and remembered (Hebrews 6:10).

• Endurance: Suffering is never wasted; He records every tear (Psalm 56:8).

• Perspective: Earthly uncertainty is temporary; eternal security is certain (2 Corinthians 4:16-18).
