Christian, how do you know you will still be a believer when you wake up in the morning? And every morning till you meet Jesus?

The biblical answer is: God will see to it.

Are you okay with that? Does this make you uneasy, admitting it depends decisively on God? I hope it is your joy and song. It really does have huge implications to believe this. Let God’s word shape your mind on it.

We Must Endure

By itself, must is not a gospel word. By itself, it feels threatening and burdensome. But it is not by itself in the Bible. “We must” occurs along with “he will” and “we will.” “We must” becomes “we will” because “God will.”

“If we have been justified by faith, we will be glorified. It is as good as done.”

The one who endures to the end will be saved. (Mark 13:13)

If we endure, we will also reign with him; if we deny him, he also will deny us. (2 Timothy 2:12)

I make known to you, brothers, the gospel . . . by which you are saved, if you hold fast the word . . . unless you believed in vain. (1 Corinthians 15:1–2)

God Will Keep You

Enduring in faith is not owing to our first profession of faith the way health is owing to a one-time vaccination. Enduring faith happens because the great physician does his sustaining work every day. We keep believing in Christ not because of antibodies left over from conversion, but because God does his life-giving, faith-preserving work every day.

He is able to keep you from stumbling and to present you blameless before the presence of his glory. (Jude 1:24)

He who began a good work in you will bring it to completion at the day of Jesus Christ. (Philippians 1:6)

I will put the fear of me in their hearts, that they may not turn from me. (Jeremiah 32:40)

[Christ] will sustain you to the end. . . . God is faithful, through whom you were called into the fellowship of his Son. (1 Corinthians 1:8–9)

The Lord will . . . bring me safely to his heavenly kingdom. (2 Timothy 4:18)

We Will Endure

Because God will see to it, we will — not just must — endure to the end. If we have been justified by faith, we will be glorified. It is as good as done.

Those whom he predestined he also called, and those whom he called he also justified, and those whom he justified he also glorified. (Romans 8:30)

Four Responses to This Security

1. Relinquish

We relinquish the burden of self-preservation. We stop thrashing and let the firefighter carry us out of the burning house. We can’t make it. He can. He will. “It is not in man who walks to direct his steps” (Jeremiah 10:23).

2. Rejoice

“Your future is secured by your omnipotent, ever-keeping God.”

Does your heart not echo the joy of Charles Spurgeon when he said, “O dear friends, one’s heart rejoices to think of those potent shalls and wills — those immoveable pillars which death and hell cannot shake — the shalls and wills of a God who ‘speaks and it is done’” (The Metropolitan Tabernacle Pulpit Sermons, Vol. IX, 364). “He who calls you is faithful; he will surely do it” (1 Thessalonians 5:24).

3. Rest

“Come to me, all who labor and are heavy laden, and I will give you rest” (Matthew 11:28). The yoke is easy and the burden is light because God says, “I will carry you, and you will rest on me.” “Even to your old age I am he, and to gray hairs I will carry you. I have made, and I will bear; I will carry and will save” (Isaiah 46:4).

4. Risk

If you know your future is secured by your omnipotent, ever-keeping God, the threats of earth and hell cannot stop you from spreading his fame. The inference Paul drew from “those whom he justified he also glorified” was “If God is for us, who can be against us?” (Romans 8:31). Therefore, we will risk “tribulation, distress, persecution, famine, nakedness, danger, and sword” (Romans 8:35). Because nothing can separate us from the love of God in Christ (Romans 8:39).
