Accepting self in Christ

I want very badly to rest and allow God to does his part but I have so much fear (doubt) that this could be real. That I do not have to move beyond the pain and exhaustion to fulfill my responsibilities and duties. His word says I do not have to do what I am not capable of but my mind says I should and I have to, the business exist on this very ideal. My body totally disagrees with my mind and is rebelling, which is causing pain sadness and exhaustion. What if I am making all of this up and sabotages the business or just being lazy and giving up. I am so confused
So thankful that God is a God of second chances...& third, & fourth, & even more chances. He loves u. God's approval is not based on your achievements. It's based soley on the fact that u r His child & He sees the BEST in u. There's nothing u can do, & there's nothing anybody can do, that will ever change your value in God's eyes. But u have to do ur part. Quit over analyzing your faults: stop taking an inventory of everything wrong with you. If you make mistakes, ask for forgiveness & then move on. Don't become overly concerned if you are not changing as quickly as you would like. Stay focused on what you can become, & God will get you to where you need to be! Ephesians 2:8 For it is by grace you have been saved, through faith...and this is not from yourselves, it is the gift of God
