James 1: 2 - 4 and 12
Humanly speaking, there is nothing joyful about trials. God uses trials and suffering to test our faith so that we may learn to be patient.
The believer who allows patience to work in his life becomes mature in Christ.
You'll have contentment, become complete and lack nothing.
You will be eager to do the Lord's work and finally in verse 12, you will have a crown of life.
May you be blessed.
