Someone once said that people are like tea bags. You have to put them into hot water before you can know how strong they are.
What a great truth! We believe we are strong and able to deal with any situation. But it is not until we face difficulty that we know the truth.
We can worry about the future and its trials, or we can trust in the great promise the Lord has left us in His Word: "We know that in all things God works for the good of those who love him, who have been called according to his purpose" (Romans 8:28).
It is interesting that the verse says "in all things" and not just "in some things." That is, even in those difficult moments when we are in the hot water being tested by the difficulties and challenges of life (things we don't understand), all will end if we trust in the Lord. That's why we need to always give Him thanks, not only in our victories, but also in adversity - not because the Lord is happy with our trials, but because we know that through them our character will be refined and we will be a little more like Him.
