(Hebrews 12:1–2) Therefore we also, since we are surrounded by so great a cloud of witnesses, let us lay aside every weight, and the sin which so easily ensnares us, and let us run with endurance the race that is set before us,
2 looking unto Jesus, the author and finisher of our faith, who for the joy that was set before Him endured the cross, despising the shame, and has sat down at the right hand of the throne of God.
Having faith in God - trusting God - seems so simple. But how do I know that I am really safe? What if I let go of God? Or what if I do something that causes God to let go of me?
Some people teach a sort of mechanical security - that if you have prayed the "sinner's prayer" with sincerity you are absolutely secure for eternity - no matter what you do after that. Other people say that is false and teach perpetual insecurity so that people won't think they can sin with impunity.
But what does the Bible say?
(John 10:27–30) My sheep hear My voice, and I know them, and they follow Me. And I give them eternal life, and they shall never perish; neither shall anyone snatch them out of My hand. My Father, who has given them to Me, is greater than all; and no one is able to snatch them out of My Father’s hand. I and my Father are one.
In Christ we have ETERNAL life. How can you have eternal life only temporarily? Christ Himself and God the Father are united in guaranteeing our security. How can we improve on that?
But we DO have doubts and fears. No matter what we KNOW - we sometimes FEEL insecure. We know that we are weak. We know that we are undeserving. We see our failures. We see the enemies we face and feel we are at risk. It is hard to rest in Christ. We are tempted to run away. We think security should be like a high wall that would surround us for our protection. Nothing could get in to harm us. We could not get out into the dangers beyond. Inside everything would be perpetually calm "and the skies are not cloudy all day."
But none of us experiences security in that way. How are we really secure?
Do you cover your eyes in the scary parts of action/adventure movies? (You know the parts I mean - Harrison Ford as Indiana Jones is facing hordes of Amazon Indians with poison darts, or a pit full of poisonous snakes, or a huge rolling boulder trap, etc.)
My point is that even though we know that the movie is not real, we identify with the characters. Since we identify with the characters we get excited when they are facing difficult situations. But throughout it all - even though our hearts are beating wildly and we are covering our eyes or yelling warnings at the screen - WE KNOW FULL WELL THAT NOTHING IS GOING TO HAPPEN TO INDIANA JONES!
How do we know? We know because he is the title character in the film. We know that he is safe because the author who wrote the script won't let anything happen to the main character of the film. The character is safe because the author wants him to be safe. (The author is planning a sequel.)
This is exactly how our security works too. God is the author of our lives - and of our salvation. He has written our story. It may include exciting, frightening, difficult, dangerous and painful chapters. But no matter what the circumstances look like, we are as safe as the Author's love for us. We have nothing to fear. He is in complete control of every aspect of our story. Like the authors of action movies - our Author has a sequel in mind for us.
(Romans 8:35–39) Who shall separate us from the love of Christ? Shall tribulation, or distress, or persecution, or famine, or nakedness, or peril, or sword?
36 As it is written: “For Your sake we are killed all day long; We are accounted as sheep for the slaughter.”
37 ¶ Yet in all these things we are more than conquerors through Him who loved us.
38 For I am persuaded that neither death nor life, nor angels nor principalities nor powers, nor things present nor things to come,
39 nor height nor depth, nor any other created thing, shall be able to separate us from the love of God which is in Christ Jesus our Lord.
So get out there and live the adventure, trusting in Jesus all the way. He is "the author and finisher of our faith."
