HOW CAN I BE SURE THAT I AM A CHRISTIAN?John 3:3 Jesus answered him, “Truly, truly, I say to you, unless one is born again he cannot see the kingdom of God.” (ESV)
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! (2 Corinthians 13:5, ESV)
1. Did a work start in you? if you confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved. (Romans 10:9)
- And I am sure of this, that he who began a good work in you will bring it to completion at the day of Jesus Christ. (Philippians 1:6)
2. Have you experienced God’s Spirit in you? In him you also, when you heard the word of truth, the gospel of your salvation, and believed in him, were sealed with the promised Holy Spirit, who is the guarantee of our inheritance until we acquire possession of it, to the praise of his glory. (Ephesians 1:13-14)
3. Is there fruit of God’s Spirit growing in you? (Read the book of 1 John)
1. Do you enjoy having fellowship w/Christ & Christians? (1 John 1:3)
2. Would people say you walk in the light or darkness? (1 John 1:6-7)
3. Do you admit and confess your sin? (1 John 1:8)
4. Are you obedient to God's Word? (1 John 2:3-5)
5. Does your life indicate you love God or the world? (1 John 2:15)
6. Is your life characterized by "doing what is right"? (1 John 2:29)
7. Do you seek to maintain a pure life? (1 John 3:3)
8. Do you see a decreasing pattern of sin in your life? (1 John 3:5-6)
[i.e. not continuing in sin as a way of life, not a total absence of sin.]
9. Do you demonstrate love for other Christians? (1 John 3:14)
10. Do you "walk the walk," vs just "talking the talk"? (1Jn 3:18-19)
11. Do you maintain a clear conscience? (1 John 3:21)
12. Do you experience victory in your Christian walk? (1 John 5:4)
4. Do you endure in the faith? They went out from us, but they were not of us; for if they had been of us, they would have continued with us. But they went out, that it might become plain that they all are not of us. (1 John 2:19)
Works of the Flesh vs. Fruits of the Spirit: What best describes you?
The “works of the flesh” are evidence for unbelief and an eternity in Hell.
The “fruit of the Spirit” evidences God’s saving work and eternity with Christ. (Galatians 5:16-24)
 Now the works of the flesh are evident: sexual immorality, impurity, sensuality,  idolatry, sorcery, enmity, strife, jealousy, fits of anger, rivalries, dissensions, divisions,  envy, drunkenness, orgies, and things like these. I warn you, as I warned you before, that those who do such things will not inherit the kingdom of God.
 But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness,  gentleness, self-control; against such things there is no law.  And those who belong to Christ Jesus have crucified the flesh with its passions and desires. Parable of the Sower:
What category of “soil” best describes your response to the good news about Jesus?
(Matthew 13:19-23 ESV)
-  When anyone hears the word of the kingdom and does not understand it, the evil one comes and snatches away what has been sown in his heart. This is what was sown along the path.
-  As for what was sown on rocky ground, this is the one who hears the word and immediately receives it with joy,  yet he has no root in himself, but endures for a while, and when tribulation or persecution arises on account of the word, immediately he falls away.
-  As for what was sown among thorns, this is the one who hears the word, but the cares of the world and the deceitfulness of riches choke the word, and it proves unfruitful.
Only the fourth ("good") soil below describes a genuine Christian.
-  As for what was sown on good soil, this is the one who hears the word and understands it. He indeed bears fruit and yields, in one case a hundredfold, in another sixty, and in another thirty.
Do You See These Three Characteristics in Your Life?
The Book of 1 John Helps Us to See Characteristics of Truly Converted and Saved Souls.
I write these things to you who believe in the name of the Son of God
that you may know that you have eternal life. (1 John 5:13)
1. Obedience to God's Commands?
- If we say we have fellowship with him while we walk in darkness, we lie and do not practice the truth. (1 John 1:6 )
- Whoever says “I know him” but does not keep his commandments is a liar, and the truth is not in him, but whoever keeps his word, in him truly the love of God is perfected. By this we may know that we are in him: whoever says he abides in him ought to walk in the same way in which he walked. (1 John 2:4-6)
- If one turns away his ear from hearing the law, even his prayer is an abomination. (Proverbs 28:9)
- No one who abides in him keeps on sinning; no one who keeps on sinning has either seen him or known him. (1 John 3:6)
- By this it is evident who are the children of God, and who are the children of the devil: whoever does not practice righteousness is not of God, nor is the one who does not love his brother. (1 John 3:10)
- For this is the love of God, that we keep his commandments. And his commandments are not burdensome. (1 John 5:3)
- Whoever says he is in the light and hates his brother is still in darkness. (1 John 2:9)
- For if you forgive others their trespasses, your heavenly Father will also forgive you, but if you do not forgive others their trespasses, neither will your Father forgive your trespasses. (Matt 6:14-15)
- If anyone loves the world, the love of the Father is not in him. (1 John 2:15)
- No one who denies the Son has the Father. (1 John 2:23)
- But if anyone does not provide for his relatives, and especially for members of his household, he has denied the faith and is worse than an unbeliever. (1 Timothy 5:8)
- Anyone who does not love does not know God, because God is love. (1 John 4:8)
