You are struggling against sin, but your struggles have not yet caused you to be killed.
You have forgotten the encouraging words that call you his children: "My child, don't think the Lord's discipline is worth nothing, and don't stop trying when he corrects you.
The Lord disciplines those he loves, and he punishes everyone he accepts as his child."
So hold on through your sufferings, because they are like a father's discipline. God is treating you as children. All children are disciplined by their fathers.
If you are never disciplined (and every child must be disciplined), you are not true children.
We have all had fathers here on earth who disciplined us, and we respected them. So it is even more important that we accept discipline from the Father of our spirits so we will have life.
Our fathers on earth disciplined us for a short time in the way they thought was best. But God disciplines us to help us, so we can become holy as he is.
We do not enjoy being disciplined. It is painful, but later, after we have learned from it, we have peace, because we start living in the right way.
You have become weak, so make yourselves strong again.
Live in the right way so that you will be saved and your weakness will not cause you to be lost.
