I read this post by "Life As Mom" part 1 and part 2, and it was what I have been feeling and going through...
Wanting to become deeper in Christ, wanting more for my marriage, and just overall of "The Grass is Greener on the Other Side".
But everybody has a different role in Christ and they are at different levels in their walk with God.
And I can not compare my life with anyone elses, it will only drag me down.
I can on the other hand, look at others walk in life and gleen areas of God I see in them, that will call me higher.
And strive to continually seeking God in all aspects of my life.
I hope you look into the links posted above, and may it minister to you as it did to me.
