If you take refuge in God, this is one passage that for some reason stuck with me when I was going through my chemo and radiation. Even now, 5 years down the road I remember it and turn to it when I feel like life is not "fair"
Romans Chapter 5
1 Therefore being justified by faith, we have peace with God through our Lord Jesus Christ:
2 By whom also we have access by faith into this grace wherein we stand, and rejoice in hope of the glory of God.
3 And not only so, but we glory in tribulations also: knowing that tribulation worketh patience;
4 And patience, experience; and experience, hope:
5 And hope maketh not ashamed; because the love of God is shed abroad in our hearts by the Holy Ghost which is given unto us.
