Psalm 27 gives me huge encouragement. It starts with a reminder that should give every follower of Christ hope and confidence, "The LORD is my light and my salvation- so why should I be afraid? The LORD is my fortress, protecting me from danger, so why should I tremble?" (vs. 1 NLT) This reminder needs to be carefully considered when we face trouble, suffering, rejection, doubt or uncertainty. Our relationship with God is much more about who He is that who we are. The fact is that the object of our faith is much more important the amount of our faith. A little trust in what is true is much more valuable than a lot of trust in something that isn't true. In this Psalm, King David knows that there is trouble and danger around him. He has enemies that want to prevent him from being successful in accomplishing the work God has for him. He writes this Psalm as a personal reminder that no matter how bleak or overwhelming things may appear at any given time, God is still strong and capable of protecting and providing for him.
The key here is to be humbly surrendered to God, and the evidence for this is obeying Him. For example, if I find myself being wrongly accused I could decide to retaliate in kind, but in doing so, I am taking a path away from God's care and protection. To defend myself with the facts is ok but when I choose to retaliate, I am saying in effect that God can't be trusted to defend or protect me. Trusting and obeying God is often counter to our natural bent but when we do we position ourselves to experience God's power to change us and to work in the circumstances of our life. In Romans 8 we see this truth expressed even more fully:
“If God is for us, who can ever be against us? 32 Since he did not spare even his own Son but gave him up for us all, won’t he also give us everything else? 33 Who dares accuse us whom God has chosen for his own? No one—for God himself has given us right standing with himself. 34 Who then will condemn us? No one—for Christ Jesus died for us and was raised to life for us, and he is sitting in the place of honor at God’s right hand, pleading for us. 35 Can anything ever separate us from Christ’s love? Does it mean he no longer loves us if we have trouble or calamity, or are persecuted, or hungry, or destitute, or in danger, or threatened with death?... No, despite all these things, overwhelming victory is ours through Christ, who loved us. 38 And I am convinced that nothing can ever separate us from God’s love. Neither death nor life, neither angels nor demons, neither our fears for today nor our worries about tomorrow—not even the powers of hell can separate us from God’s love. 39 No power in the sky above or in the earth below—indeed, nothing in all creation will ever be able to separate us from the love of God that is revealed in Christ Jesus our Lord.”
