Job 5:7 tells us: "Man is born to trouble as surely as sparks fly upward." Yes, suffering is the burden of humanity.
Perhaps, your heart is aching today, and you say, "What can I do with this burden?" Often God allows us to have burdens to exercise our faith. People who run from problems, for example, those who try to fill the valleys in their lives with drugs or alcohol, are really missing a blessing.
God works to make us more valuable through difficulties and hardships. A bar of iron may be worth $5.00. Make it into horseshoes, and it will be worth $10.00. Make it into needles, and it might be worth hundreds of dollars. Make it into balance wheels for watches and its value might run to tens of thousands of dollars. To be worth more, it has to be refined, superheated, drawn out, and purified.
Our faith is like that; it grows under pressure (disappointments, trials, difficulties) far more than when things are comfortable. Paul underlined this in Romans chapter 5 where he tells us to rejoice in our sufferings because they are good for us. They teach us patience, and patience develops strength of character and helps us to trust God more each time we exercise it until, finally, our faith and hope are strong and steady.
Accordingly, we're able to hold our heads high no matter what happens. We know all is well because God loves us. Therefore, strengthen your faith, bear your burden gracefully; trust in God, and He will see you through to the end.
