Man is not promised an endless supply of strength for him to store up. Rather, God promises to provide the necessary grace and strength for the present trials.
Change often results in fear. As such, it must be met with strength. Failure to do so can breed panic that only God's strength can overcome.
During times of battle, believers commonly find themselves to be underdogs. Faith, however, refuses to retreat and trusts God to overcome superior foes.
Though the means of worldly safety have changed throughout time, people have always put their trust in various things to offer temporary safety. The Bible depicts those who trusted in fenced walls (Deuteronomy 28:52), nations (Isaiah 30:2-3), horses, horsemen and chariots (Isaiah 31:1), weapons (Psalm 44:6), and mountains (Amos 6:1). People today place their trust in weapons, security systems, governments, insurance policies, and even medicines. Though the sources of trust have changed, the Lord remains just as grieved today when men place their trust upon the things of this world rather than upon Him. Ultimately, every source of worldly safety will fail, often in the moment we perceive as our greatest time of need.
Most people in the world would not consider themselves rich. For this reason, they might think it impossible to trust in riches. They might point to their meager bank accounts as evidence. Yet, a person does not have to be rich in order to trust in riches. No matter the amount of riches or treasures that one might have, there is a very real danger in trusting in those things. Riches, however, are of little value. According to Psalm 49:6-8, riches are of no assistance in man’s greatest need, the redemption of his soul. Not only can riches not help, but they are uncertain (1 Timothy 6:17). Those who trust in them will be disappointed and will ultimately fall (Proverbs 11:28). Even if riches increase, man should not set his heart upon them (Psalm 62:10).
