“Therefore, since we have been justified by faith, we have peace with God through our Lord Jesus Christ. 2 Through him we have also obtained access by faith into this grace in which we stand, and we rejoice in hope of the glory of God. Not only that, but we rejoice in our sufferings, knowing that suffering produces endurance, and endurance produces character, and character produces hope, and hope does not put us to shame, because God’s love has been poured into our hearts through the Holy Spirit who has been given to us.” – Romans 5:1-5
Believers rejoice is suffering because it confirms our salvation. When we do not fall away during trials and tribulations that perseverance is also of God and is the proof.
“But blessed is the one who trusts in the Lord, whose confidence is in him. They will be like a tree planted by the water that sends out its roots by the stream. It does not fear when heat comes; its leaves are always green. It has no worries in a year of drought and never fails to bear fruit.” –
Jeremiah 17:7-8
