Galatians 2:20 "I have been crucified with Christ; and it is no longer I who live but Christ lives in me; and the life which I now live in the flesh I live by faith in the Son of God, who loved me and delivered Himself up for me."
Even though the first part of this verse is very hard to do, I find comfort that I do not have to do the job that God has for me alone. God in me makes the best me i.e. best wife, best mom, best friend. My job is to make sure I give my will to God so that God's will can be lived out in me. This is a big task especially when I can be stubborn at times but is much less stressful then trying to go at life all by myself.
