12 And because lawlessness will be increased, the love of many will grow cold. 13 But the one who endures to the end will be saved.
Matthew 24:12-13 (ESV)
7 Do not be deceived: God is not mocked, for whatever one sows, that will he also reap. 8 For the one who sows to his own flesh will from the flesh reap corruption, but the one who sows to the Spirit will from the Spirit reap eternal life. 9 And let us not grow weary of doing good, for in due season we will reap, if we do not give up.
Galatians 6:7-9 (ESV)
12 if we endure, we will also reign with him;
if we deny him, he also will deny us;
2 Timothy 2:12 (ESV)
35 Therefore do not throw away your confidence, which has a great reward. 36 For you have need of endurance, so that when you have done the will of God you may receive what is promised. 37 For,
“Yet a little while,
and the coming one will come and will not delay;
38 but my righteous one shall live by faith,
and if he shrinks back,
my soul has no pleasure in him.”
39 But we are not of those who shrink back and are destroyed, but of those who have faith and preserve their souls.
Hebrews 10:35-39 (ESV)
10 Do not fear what you are about to suffer. Behold, the devil is about to throw some of you into prison, that you may be tested, and for ten days you will have tribulation. Be faithful unto death, and I will give you the crown of life. 11 He who has an ear, let him hear what the Spirit says to the churches. The one who conquers will not be hurt by the second death.’
Revelation 2:10-11 (ESV)
