I'm not sure if my thought is actually on being challenged or being frustrated. I actually think it's a bit of both. The past two years of our lives have brought about both some unexpected challenges that have created some frustration. What they have also brought about is a determination, a inner voice that says, "you've come too far, faced too much, and experience far too much grace to allow your present circumstances to cloud what God has in store for you!"
If you listen to many people talk, you'll quickly find that many of them feel much like I do, they've got stuff, and the stuff is often overwhelming. I am reminded of the words of the Apostle Paul when he said, "None of these things move me...Forgetting what is behind, and looking to what is ahead...I press toward the mark!"
It is easy to quit, to give up on the inside, but life isn't about quitting, it's about continuing, it's about progressing. So challenges and frustrations aside, we keep pushing...we will get there...eventually:)
