To be ‘born again’ in scriptural terms is to be born first of water and then of the spirit.
John 3:3 Jesus answered and said unto him, Verily, verily, I say unto thee, Except a man be born again, he cannot see the kingdom of God… 5… except a man be born of water and of the Spirit, he cannot enter into the kingdom of God.
To be born of water we must be immersed in water into Jesus Christ, for the remission of our sins, in the name of the Father, Son and Holy Spirit.
Matthew 28:19 Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Spirit:
Acts 22:16 And now why tarriest thou? arise, and be baptized, and wash away thy sins, calling on the name of the Lord.
Romans 6:3 Know ye not, that so many of us as were baptized into Jesus Christ were baptized into his death? 4 Therefore we are buried with him by baptism into death: that like as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life.
To be born again by immersion in water is quickly done, but to be born of the spirit is the work of a lifetime.
1 Peter 1:23 Being born again, not of corruptible seed, but of incorruptible, by the word of God, which liveth and abideth for ever.
A change must take place in the spirit of our minds and this change doesn’t happen overnight.
We must apply ourselves to the scriptures and make a conscious effort to live by the commandments of Jesus Christ.
Romans 12:2 And be not conformed to this world: but be ye transformed by the renewing of your mind, that ye may prove what is that good, and acceptable, and perfect, will of God.
Ephesians 4:23 And be renewed in the spirit of your mind;
Our nature does not change, there is a battle to be fought in our minds to conform our will to God’s will.
Paul describes it thus:
Romans 7:18 For I know that in me (that is, in my flesh,) dwelleth no good thing: for to will is present with me; but how to perform that which is good I find not. 19 For the good that I would I do not: but the evil which I would not, that I do. 20 Now if I do that I would not, it is no more I that do it, but sin that dwelleth in me. 21 I find then a law, that, when I would do good, evil is present with me. 22 For I delight in the law of God after the inward man: 23 But I see another law in my members, warring against the law of my mind, and bringing me into captivity to the law of sin which is in my members. 24 O wretched man that I am! who shall deliver me from the body of this death? 25 I thank God through Jesus Christ our Lord. So then with the mind I myself serve the law of God; but with the flesh the law of sin.
The temptation to sin comes from inside of us.
Mark 7:21 For from within, out of the heart of men, proceed evil thoughts, adulteries, fornications, murders, 22 Thefts, covetousness, wickedness, deceit, lasciviousness, an evil eye, blasphemy, pride, foolishness: 23 All these evil things come from within, and defile the man.
James 1:14 But every man is tempted, when he is drawn away of his own lust, and enticed. 15 Then when lust hath conceived, it bringeth forth sin: and sin, when it is finished, bringeth forth death. 16 Do not err, my beloved brethren.
Repentance and baptism into Christ are a new beginning.
John 15:14 Ye are my friends, if ye do whatsoever I command you.
Luke 6:46 And why call ye me, Lord, Lord, and do not the things which I say? 47 Whosoever cometh to me, and heareth my sayings, and doeth them, I will shew you to whom he is like: 48 He is like a man which built an house, and digged deep, and laid the foundation on a rock: and when the flood arose, the stream beat vehemently upon that house, and could not shake it: for it was founded upon a rock. 49 But he that heareth, and doeth not, is like a man that without a foundation built an house upon the earth; against which the stream did beat vehemently, and immediately it fell; and the ruin of that house was great.
Living by Christ’s commandments is described as ‘walking in the light’.
We cannot live a sinless life.
After baptism we will still sin, but provided we are making a conscious effort to ‘walk in the light’ our sins will be forgiven by confession in prayer.
1 John 1:7 But if we walk in the light, as he is in the light, we have fellowship one with another, and the blood of Jesus Christ his Son cleanseth us from all sin. 8 If we say that we have no sin, we deceive ourselves, and the truth is not in us. 9 If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.
Paul advises the Philippians to ‘work out their salvation’ by obeying the gospel.
Philippians 2:12 Wherefore, my beloved, as ye have always obeyed, not as in my presence only, but now much more in my absence, work out your own salvation with fear and trembling.
Salvation depends not on living a sinless life but by having faith in Jesus Christ as the redeemer.
Faith in him will be counted for righteousness.
Romans 4:13 For the promise, that he should be the heir of the world, was not to Abraham, or to his seed, through the law, but through the righteousness of faith… 23 Now it was not written for his sake alone, that it was imputed to him; 24 But for us also, to whom it shall be imputed, if we believe on him that raised up Jesus our Lord from the dead; 25 Who was delivered for our offences, and was raised again for our justification.
Faith requires work in order to exist.
James 2:17 Even so faith, if it hath not works, is dead, being alone. 18 Yea, a man may say, Thou hast faith, and I have works: shew me thy faith without thy works, and I will shew thee my faith by my works.
Matthew 5:16 Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven.
2 Corinthians 5:17 Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new.
Baptised into Christ we are a new creation in the sight of God.
We have gone from Adam into Christ.
Our nature is not changed supernaturally.
The onus is upon us to actively change the way that we live.
2 Corinthians 7:1 Having therefore these promises, dearly beloved, let us cleanse ourselves from all filthiness of the flesh and spirit, perfecting holiness in the fear of God.
Hebrews 4:1 Let us therefore fear, lest, a promise being left us of entering into his rest, any of you should seem to come short of it.
Titus 2:11 For the grace of God that bringeth salvation hath appeared to all men, 12 Teaching us that, denying ungodliness and worldly lusts, we should live soberly, righteously, and godly, in this present world;
1 Peter 2:11 Dearly beloved, I beseech you as strangers and pilgrims, abstain from fleshly lusts, which war against the soul;
Exhortation and self-examination are necessary if we would attain to eternal life.
This is reflected in meeting regularly to share bread and wine in remembrance of Christ’s sacrifice.
1 Corinthians 11:28 But let a man examine himself, and so let him eat of that bread, and drink of that cup.
I hope this helps.
