Yes, we must be forever joyful inspite of our suffering because suffering makes us even more stronger and forms us into a better person.1Peter 2:21 "For to this you have been called, because Christ also suffered for you,leaving you an example, so that you might follow in his steps".1Tess 5:16-18 "Rejoice always,pray continually,give thanks in all circumstances for this is Gods will for you in Christ Jesus".
