A spiritually mature person has a different view of trials and tribulations than an immature person. A spiritually mature person handles tribulations by keeping joy and trusting God in the midst of it. Even though the enemy may be bringing it, God is able to work good out of it, and very often we learn things about ourselves during trials that we would never see any other way.
We should thank God in the midst of our trials instead of murmuring and complaining and feeling sorry for ourselves. Look at your troubles in a new way. Don’t act any differently when you are going through a storm than you would if life were full of rainbows (you don’t get rainbows until you’ve been through a storm!). And remember, with every temptation, He also provides a way out (see 1 Corinthians 10:13).
