At church last Sunday the verses were these below, the Reformation ESV study Bible had a note, so I looked it up:
2 Corinthians 13 English Standard Version (ESV)
13 This is the third time I am coming to you. Every charge must be established by the evidence of two or three witnesses. 2 I warned those who sinned before and all the others, and I warn them now while absent, as I did when present on my second visit, that if I come again I will not spare them— 3 since you seek proof that Christ is speaking in me. He is not weak in dealing with you, but is powerful among you. 4 For he was crucified in weakness, but lives by the power of God. For we also are weak in him, but in dealing with you we will live with him by the power of God.
5 Examine yourselves, to see whether you are in the faith. Test yourselves. Or do you not realize this about yourselves, that Jesus Christ is in you?—unless indeed you fail to meet the test! 6 I hope you will find out that we have not failed the test. 7 But we pray to God that you may not do wrong—not that we may appear to have met the test, but that you may do what is right, though we may seem to have failed. 8 For we cannot do anything against the truth, but only for the truth. 9 For we are glad when we are weak and you are strong. Your restoration is what we pray for. 10 For this reason I write these things while I am away from you, that when I come I may not have to be severe in my use of the authority that the Lord has given me for building up and not for tearing down.
TEXT NOTES: 13:5 Examine . . . Test. See 1 Cor. 11:28; Gal. 6:4.
Paul’s words help clarify the doctrine of assurance of faith. Paul asks the Corinthians to examine their own lives for evidence of salvation.
Such evidence would include trust in Christ (Heb. 3:6),
5 Now Moses was faithful in all God’s house as a servant, to testify to the things that were to be spoken later,6 but Christ is faithful over God’s house as a son. And we are his house if indeed we hold fast our confidence and our boasting in our hope.
obedience to God (Matt. 7:21),
21 “Not everyone who says to me, ‘Lord, Lord,’ will enter the kingdom of heaven, but the one who does the will of my Father who is in heaven.
growth in holiness (Heb. 12:14; 1 John 3:3),
14 Strive for peace with everyone, and for the holiness without which no one will see the Lord.
3 Jesus answered him, “Truly, truly, I say to you, unless one is born again[b] he cannot see the kingdom of God.”
the fruit of the Spirit (Gal. 5:22, 23),
22 But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, 23 gentleness, self-control; against such things there is no law. 24 And those who belong to Christ Jesus have crucified the flesh with its passions and desires.
love for other Christians (1 John 3:14),
14 We know that we have passed out of death into life, because we love the brothers. Whoever does not love abides in death.
Positive influence on others (Matt. 5:16),
14 “You are the light of the world. A city set on a hill cannot be hidden. 15 Nor do people light a lamp and put it under a basket, but on a stand, and it gives light to all in the house. 16 In the same way, let your light shine before others, so that[b] they may see your good works and give glory to your Father who is in heaven.
adhering to the apostolic teaching (1 John 4:2),
Beloved, do not believe every spirit, but test the spirits to see whether they are from God, for many false prophets have gone out into the world. 2 By this you know the Spirit of God: every spirit that confesses that Jesus Christ has come in the flesh is from God, 3 and every spirit that does not confess Jesus is not from God. This is the spirit of the antichrist, which you heard was coming and now is in the world already.
and the testimony of the Holy Spirit within them (Rom. 8:15, 16).
12 So then, brothers,[e] we are debtors, not to the flesh, to live according to the flesh. 13 For if you live according to the flesh you will die, but if by the Spirit you put to death the deeds of the body, you will live. 14 For all who are led by the Spirit of God are sons[f] of God. 15 For you did not receive the spirit of slavery to fall back into fear, but you have received the Spirit of adoption as sons, by whom we cry, “Abba! Father!” 16 The Spirit himself bears witness with our spirit that we are children of God, 17 and if children, then heirs—heirs of God and fellow heirs with Christ, provided we suffer with him in order that we may also be glorified with him.
Do you have all that? Do I have all that? Trust, obedience, growth, fruit, love? Sometimes I think, yes…sometimes, no.
If we don’t think/feel/see these assurances, then how do we know we are saved?
