God loves us, and He is always looking out for our eternal benefit. We are fond of quoting Romans 8:28, which says, "And we know that God causes everything to work together for the good of those who love God and are called according to his purpose for them." But after verse 28 comes verse 29: "For God knew his people in advance, and he chose them to become like his Son, so that his Son would be the firstborn among many brothers and sisters."
If we isolate verse 28, we may get the wrong idea and think that everything always has to turn out nicely. We might think that whatever happens, it will get better, and we can tie it all up with a nice little bow and say, "You see? This bad thing happened, and it turned into a good thing. And now. . . ."
That is true of a lot of things in life. But then there are things that are bad, and they stay bad. And they always will be bad. So even when what we are going through is difficult, the Bible says, "For our present troubles are small and won't last very long. Yet they produce for us a glory that vastly outweighs them and will last forever!" (2 Corinthians 4:17).
The ultimate good is not our temporal happiness. The ultimate good is that we are going to be like Jesus Christ. That is God's objective. As the apostle John reminds us, "But he has not yet shown us what we will be like when Christ appears. But we do know that we will be like him, for we will see him as he really is."
So there are things in life that will make sense. And there are other things that won't make sense. But just remember this: God loves you, and He is always looking out for your eternal benefit.
