What then shall we say to these things? If God is for us, who can be against us? He who did not spare his own Son but gave him up for us all, how will he not also with him graciously give us all things?… For I am sure that neither death nor life, nor angels nor rulers, nor things present nor things to come, nor powers, nor height nor depth, nor anything else in all creation, will be able to separate us from the love of God in Christ Jesus our Lord.
(Romans 8:31-32,38-39 ESV)
I cannot imagine living the Christian life on any other basis than this. If the Father loves me so much that he did not spare his own Son but delivered him up to be crucified for me, no further guarantee is needed of his wholehearted and permanent commitment to me and to my blessing.
Whatever happens to me must be seen in that light. Yes, my deepest fears may become realities. I may not be able to understand what God is doing in or to my life; he may seem to be hiding his face from me; my heart may be broken. But can I not trust the One who demonstrated his love for me? When I was helpless in my sin he sent Christ to die for me (Rom. 5:8). If he has done that, will he not work all things together for my good? Will he withhold any thing that is ultimately for the good of those who trust him?
In this way, Christ’s death becomes the rod, the cudgel that breaks the necks of the fears that are the enemies of my peace; his word becomes the staff by which he holds on to me and rescues me from danger.
