If there is one thing God has been drilling into my head these past few years it is contentment. Philippians 2:14 and 4:12-13 are constantly being brought to my mind. Along with questions like, "how do I not complain when the upstairs neighbor's dog's poop falls on our patio?" Or, "how am I supposed to be content with all 4 of us living in my one bedroom apartment, and I'm doing all our laundry by hand, when I hear others around me complain about all the laundry their washing machine has to do after they return home from taking a cruise?"
These helped me through this.
1) I deserve hell. I deserve much worse than whatever trails I am going through.
2) These trails are actually for my benefit. God loves me enough to put things in my life that make me turn to HIM.
3) I am constantly reminded of how much I need Christ and the gospel. I am as much in need of the gospel to live a Christian life, as I was in need of it to give me life.
4) All things come together for good to them that love God and are called according to His purpose.
