Therefore, my beloved brethren, be steadfast, immovable, always abounding in the work of the Lord, knowing that your toil is not in vain in the Lord. 1 Corinthians 15:58

Often times as Christians we probably feel our work for Jesus is in vein. We work very hard every day to live for The Lord, however sometimes we don’t see the fruits of our labor for a long time. Paul is preaching a message of hope and perseverance to his fellow Christians. Your labor for God is not in vain, God knows every work you has done and your works are being used to prepare the Kingdom of God

Knowing that your (kopos) is not  (kenos)

The Greek word kopos also means pains, labor, toil

The Greek word kenos means empty

Knowing that your (Pains) Is Not (Empty)

The work your are doing for Jesus is not empty, its not fruitless. However during this time, you are going to feel pains, your going to labor , you are going to toil. But your work is for God and nobody else. When you keep the right perspective on your labor, they you will always be satisfied

and if Christ has not been raised, then our preaching is vain, your faith also is vain. 1 Corinthians 15:14

The Resurrection is the center of Christianity, because without the Resurrection of Christ there is no hope. Without the Resurrection of Christ there is no purpose for anything your doing as a Christian. However since we know the Resurrection is true, we know that our works are not in vein (kenon) (empty) but our works are fulfilling Gods Kingdom

Kenon and Kenos mean the same thing in Greek meaning Empty

If Christ has not been raised (Resurrected) then our preaching is  (Kenon) (Empty) and your Faith is also (Kenon) (Empty)

However since we know Christ has been raised from the dead , our works and faith are fulfilling in glorifying God Amen!
