I don't like problems or challenges any more than you do. However, if our Father is truly good (and He is) there must be a purpose. Peter knew something about challenges. He had been tried and arrested for his faith. Later in his life he wrote this:
So be truly glad. There is wonderful joy ahead, even though you have to endure many trials for a little while. These trials will show that your faith is genuine. It is being tested as fire tests and purifies gold—though your faith is far more precious than mere gold. So when your faith remains strong through many trials, it will bring you much praise and glory and honor on the day when Jesus Christ is revealed to the whole world. (1 Peter 1:6-7 NLT)
That is amazing. I want to have a real living faith. More than just words. Like gold it should be pure, valuable, precious. Even when I don't understand things. Especially then.
