Don’t Quit Now

1 Corinthians 15:1-2 Now I want to make clear for you, brothers and sisters, the gospel that I preached to you, that you received and on which you stand, and by which you are being saved, if you hold firmly to the message I preached to you—unless you believed in vain.1 Corinthians 15:10 But by the grace of God I am what I am, and his grace to me has not been in vain. In fact, I worked harder than all of them—yet not I, but the grace of God with me.
1 Corinthians 15:12-20 Now if Christ is preached, that He has been raised from the dead, how do some among you say that there is no resurrection of the dead? But if there is no resurrection of the dead, not even Christ has been raised; and if Christ has not been raised, then our preaching is vain, your faith also is vain. Moreover, we are even found to be false witnesses of God, because we testified against God that He raised Christ, whom He did not raise, if in fact the dead are not raised. For if the dead are not raised, not even Christ has been raised; and if Christ has not been raised, your faith is worthless; you are still in your sins. Then those also who have fallen asleep in Christ have perished. If we have hoped in Christ in this life only, we are of all men most to be pitied. But now Christ has been raised from the dead, the first fruits of those who are asleep. 
1 Corinthians 15:54-58 Now when this perishable puts on the imperishable, and this mortal puts on immortality, then the saying that is written will happen, “Death has been swallowed up in victory.” “Where, O death, is your victory?
Where, O death, is your sting?” The sting of death is sin, and the power of sin is the law. But thanks be to God, who gives us the victory through our Lord Jesus Christ! So then, dear brothers and sisters, be firm. Do not be moved! Always be outstanding in the work of the Lord, knowing that your labor is not in vain in the Lord.
