You can make them redemptive by uniting them with the sufferings of Christ. In Colosians Paul says “In my own body I fill up what is still lacking in the suffferings of Christ, for the sake of his body, the Church.” The following prayer may be helpful.
Unite my pain with yours.
In you do I place my hope.
In faithfulness you have afflicted me.
You wound, but you also heal.
You give and you take away.
Hallowed be your name.
