But because you are partakers of Christ's sufferings, rejoice; that at the revelation of his glory also you may rejoice with exceeding joy.
inasmuch as ye are partakers of Christ’s sufferings: Rejoice "inasmuch" or "insofar as" it is for Christ’s sake. If Christians suffer because they have committed wrong, they should not rejoice. Righteousness sake is the basis of the suffering of God’s people. The primary reason for suffering is because of union with the Lord.
