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.
1. Atonement for sin
1 Peter 1:18-20
For you know that it was not with perishable things such as silver or gold that you were redeemed from the empty way of life handed down to you from your ancestors, 19 but with the precious blood of Christ, a lamb without blemish or defect. 20 He was chosen before the creation of the world, but was revealed in these last times for your sake.
For he chose us in him before the creation of the world to be holy and blameless in his sight. In love 5 he predestined us for adoption to sonship through Jesus Christ, in accordance with his pleasure and will— 6 to the praise of his glorious grace, which he has freely given us in the One he loves. 7 In him we have redemption through his blood, the forgiveness of sins, in accordance with the riches of God’s grace
2. Atonement involves
Galatians 5:1 It is for freedom that Christ has set us free. Stand firm, then, and do not let yourselves be burdened again by a yoke of slavery.
Colossians 1:9-14 For this reason, since the day we heard about you, we have not stopped praying for you. We continually ask God to fill you with the knowledge of his will through all the wisdom and understanding that the Spirit gives, 10 so that you may live a life worthy of the Lord and please him in every way: bearing fruit in every good work, growing in the knowledge of God, 11 being strengthened with all power according to his glorious might so that you may have great endurance and patience, 12 and giving joyful thanks to the Father, who has qualified you to share in the inheritance of his holy people in the kingdom of light. 13 For he has rescued us from the dominion of darkness and brought us into the kingdom of the Son he loves, 14 in whom we have redemption, the forgiveness of sins.
For if, while we were God’s enemies, we were reconciled to him through the death of his Son, how much more, having been reconciled, shall we be saved through his life! 11 Not only is this so, but we also boast in God through our Lord Jesus Christ, through whom we have now received reconciliation.
Hebrews 2:17-18 For this reason he had to be made like them, fully human in every way, in order that he might become a merciful and faithful high priest in service to God, and that he might make atonement for the sins of the people. 18 Because he himself suffered when he was tempted, he is able to help those who are being tempted.
1 John 2:2
He is the atoning sacrifice for our sins, and not only for ours but also for the sins of the whole world.
1 John 4:10-11
This is love: not that we loved God, but that he loved us and sent his Son as an atoning sacrifice for our sins. 11 Dear friends, since God so loved us, we also ought to love one another.
For if, by the trespass of the one man, death reigned through that one man, how much more will those who receive God’s abundant provision of grace and of the gift of righteousness reign in life through the one man, Jesus Christ! 18 Consequently, just as one trespass resulted in condemnation for all people, so also one righteous act resulted in justification and life for all people. 19 For just as through the disobedience of the one man the many were made sinners, so also through the obedience of the one man the many will be made righteous.
20 The law was brought in so that the trespass might increase. But where sin increased, grace increased all the more, 21 so that, just as sin reigned in death, so also grace might reign through righteousness to bring eternal life through Jesus Christ our Lord.
If you declare with your mouth, “Jesus is Lord,” and believe in your heart that God raised him from the dead, you will be saved. 10 For it is with your heart that you believe and are justified, and it is with your mouth that you profess your faith and are saved.
