2 Timothy 2:10
Therefore I endure everything for the sake of the elect, that they too may obtain the salvation that is in Christ Jesus, with eternal glory.
2 Peter 1:10
10 Therefore, my brothers and sisters,[The Greek word for brothers and sisters (adelphoi) refers here to believers, both men and women, as part of God’s family.] make every effort to confirm your calling and election. For if you do these things, you will never stumble, 11 and you will receive a rich welcome into the eternal kingdom of our Lord and Savior Jesus Christ.
1 Corinthians 9:27
24 Do you not know that those who run in a race all run, but only one receives the prize? Run in such a way that you may win. 25 Everyone who competes in the games exercises self-control in all things. They then do it to receive a perishable wreath, but we an imperishable. 26 Therefore I run in such a way, as not without aim;but I discipline my body and make it my slave, so that, after I have preached to others, I myself will not be disqualified.
2 Timothy 4:7
I have fought the good fight, I have finished the race, I have kept the faith.
James 5:
17 Elijah was a human being, even as we are. He prayed earnestly that it would not rain, and it did not rain on the land for three and a half years. 18 Again he prayed, and the heavens gave rain, and the earth produced its crops.
19 My brothers and sisters, if one of you should wander from the truth and someone should bring that person back, 20 remember this: Whoever turns a sinner from the error of their way will save them from death and cover over a multitude of sins.
1 Timothy 4:16
Watch your life and doctrine closely. Persevere in them, because if you do, you will save both yourself and your hearers.
James 2:14
[ Faith and Deeds ] What good is it, my brothers and sisters, if someone claims to have faith but has no deeds? Can such faith save them?
Hebrews 3:
12 See to it, brothers and sisters, that none of you has a sinful, unbelieving heart that turns away from the living God. 13 But encourage one another daily, as long as it is called “Today,” so that none of you may be hardened by sin’s deceitfulness. 14 We have come to share in Christ, if indeed we hold our original conviction firmly to the very end.
