So often we ask for God to work through us. We ask for His will, not ours to be done. We ask for patience, understanding, wisdom... We call out to Him, "Lord, I believe! Help my unbelief!" Then, things start to happen. Kids start acting up, jobs are lost, we face difficult relationship problems, sickness strikes... the list goes on and on. Life gets HARD and then we question God, "WHY?!" Did you ever think that God is giving you opportunities? Those crazy kids are giving you a chance to practice patience. That lost job is allowing you to open your mind up and understand things that you normally wouldn't even try to understand because you were so wrapped up in your career. That relationship that is causing so many sleepless nights is giving you a foundation of wisdom for helping others in the future. Yes, those times are difficult, but God's working in you and giving you an opportunity to grow to be more like Him.
Romans 8:28-29 (ESV)
And we know that for those who love God all things work together for good, for those who are called according to his purpose. 29 For those whom he foreknew he also predestined to be conformed to the image of his Son, in order that he might be the firstborn among many brothers.
Be encouraged! With each trial, you are becoming more like the image of Jesus... and that is a GREAT thing!
