2 Corinthians 1:18-22
18 But as surely as God is faithful, our message to you is not “Yes†and “No.†19 For the Son of God, Jesus Christ, who was preached among you by us—by me and Silas[a] and Timothy—was not “Yes†and “No,†but in him it has always been “Yes.†20 For no matter how many promises God has made, they are “Yes†in Christ. And so through him the “Amen†is spoken by us to the glory of God. 21 Now it is God who makes both us and you stand firm in Christ. He anointed us, 22 set his seal of ownership on us, and put his Spirit in our hearts as a deposit, guaranteeing what is to come.
Romans 8:34
34 Who then is the one who condemns? No one. Christ Jesus who died—more than that, who was raised to life—is at the right hand of God and is also interceding for us.
Romans 8:9
9 You, however, are not in the realm of the flesh but are in the realm of the Spirit, if indeed the Spirit of God lives in you. And if anyone does not have the Spirit of Christ, they do not belong to Christ.
1 John 5:18
18 We know that anyone born of God does not continue to sin; the One who was born of God keeps them safe, and the evil one cannot harm them.
