Many of us will struggle as we live but we can overcome by enduring in our faith and confessing our sin. Psalm 51 is an excellent confession for every believer to read. The 1st chapter of 1st John shows we have a struggle according to our individual condition see below:
1 John 1
King James Version (KJV)
1 John 1
1That which was from the beginning, which we have heard, which we have seen with our eyes, which we have looked upon, and our hands have handled, of the Word of life;
2(For the life was manifested, and we have seen it, and bear witness, and shew unto you that eternal life, which was with the Father, and was manifested unto us
3That which we have seen and heard declare we unto you, that ye also may have fellowship with us: and truly our fellowship is with the Father, and with his Son Jesus Christ.
4And these things write we unto you, that your joy may be full.
5This then is the message which we have heard of him, and declare unto you, that God is light, and in him is no darkness at all.
6If we say that we have fellowship with him, and walk in darkness, we lie, and do not the truth:
7But 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.
8If we say that we have no sin, we deceive ourselves, and the truth is not in us.
9If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.
10If we say that we have not sinned, we make him a liar, and his word is not in us.
In our endurance, by faith we will overcome as St. Paul assures us in Romans 8:
Romans 8
King James Version (KJV)
Romans 8
1There is therefore now no condemnation to them which are in Christ Jesus, who walk not after the flesh, but after the Spirit.
2For the law of the Spirit of life in Christ Jesus hath made me free from the law of sin and death.
3For what the law could not do, in that it was weak through the flesh, God sending his own Son in the likeness of sinful flesh, and for sin, condemned sin in the flesh:
4That the righteousness of the law might be fulfilled in us, who walk not after the flesh, but after the Spirit.
5For they that are after the flesh do mind the things of the flesh; but they that are after the Spirit the things of the Spirit.
6For to be carnally minded is death; but to be spiritually minded is life and peace.
7Because the carnal mind is enmity against God: for it is not subject to the law of God, neither indeed can be.
8So then they that are in the flesh cannot please God.
9But ye are not in the flesh, but in the Spirit, if so be that the Spirit of God dwell in you. Now if any man have not the Spirit of Christ, he is none of his.
10And if Christ be in you, the body is dead because of sin; but the Spirit is life because of righteousness.
11But if the Spirit of him that raised up Jesus from the dead dwell in you, he that raised up Christ from the dead shall also quicken your mortal bodies by his Spirit that dwelleth in you.
12Therefore, brethren, we are debtors, not to the flesh, to live after the flesh.
13For if ye live after the flesh, ye shall die: but if ye through the Spirit do mortify the deeds of the body, ye shall live.
14For as many as are led by the Spirit of God, they are the sons of God.
15For ye have not received the spirit of bondage again to fear; but ye have received the Spirit of adoption, whereby we cry, Abba, Father.
16The Spirit itself beareth witness with our spirit, that we are the children of God:
17And if children, then heirs; heirs of God, and joint-heirs with Christ; if so be that we suffer with him, that we may be also glorified together.
18For I reckon that the sufferings of this present time are not worthy to be compared with the glory which shall be revealed in us.
19For the earnest expectation of the creature waiteth for the manifestation of the sons of God.
20For the creature was made subject to vanity, not willingly, but by reason of him who hath subjected the same in hope,
21Because the creature itself also shall be delivered from the bondage of corruption into the glorious liberty of the children of God.
22For we know that the whole creation groaneth and travaileth in pain together until now.
23And not only they, but ourselves also, which have the firstfruits of the Spirit, even we ourselves groan within ourselves, waiting for the adoption, to wit, the redemption of our body.
24For we are saved by hope: but hope that is seen is not hope: for what a man seeth, why doth he yet hope for?
25But if we hope for that we see not, then do we with patience wait for it.
26Likewise the Spirit also helpeth our infirmities: for we know not what we should pray for as we ought: but the Spirit itself maketh intercession for us with groanings which cannot be uttered.
27And he that searcheth the hearts knoweth what is the mind of the Spirit, because he maketh intercession for the saints according to the will of God.
28And we know that all things work together for good to them that love God, to them who are the called according to his purpose.
29For whom he did foreknow, he also did predestinate to be conformed to the image of his Son, that he might be the firstborn among many brethren.
30Moreover whom he did predestinate, them he also called: and whom he called, them he also justified: and whom he justified, them he also glorified.
31What shall we then say to these things? If God be for us, who can be against us?
32He that spared not his own Son, but delivered him up for us all, how shall he not with him also freely give us all things?
33Who shall lay any thing to the charge of God's elect? It is God that justifieth.
34Who is he that condemneth? It is Christ that died, yea rather, that is risen again, who is even at the right hand of God, who also maketh intercession for us.
35Who shall separate us from the love of Christ? shall tribulation, or distress, or persecution, or famine, or nakedness, or peril, or sword?
36As it is written, For thy sake we are killed all the day long; we are accounted as sheep for the slaughter.
37Nay, in all these things we are more than conquerors through him that loved us.
38For I am persuaded, that neither death, nor life, nor angels, nor principalities, nor powers, nor things present, nor things to come,
39Nor height, nor depth, nor any other creature, shall be able to separate us from the love of God, which is in Christ Jesus our Lord.
We must pray for others as well as ourselves:
1 Timothy 2:1
King James Version (KJV)
1 Timothy 2
1I exhort therefore, that, first of all, supplications, prayers, intercessions, and giving of thanks, be made for all men;
The works we can do in living our faith & overcome sin as best we can: (donating to a food bank for ex.)
Isaiah 58
King James Version (KJV)
7Is it not to deal thy bread to the hungry, and that thou bring the poor that are cast out to thy house? when thou seest the naked, that thou cover him; and that thou hide not thyself from thine own flesh?
8Then shall thy light break forth as the morning, and thine health shall spring forth speedily: and thy righteousness shall go before thee; the glory of the LORD shall be thy reward.
In our struggle the Lord gives us His promise of the Holy Spirit:
John 14:14-16
King James Version (KJV)
14If ye shall ask any thing in my name, I will do it.
15If ye love me, keep my commandments.
16And I will pray the Father, and he shall give you another Comforter, that he may abide with you for ever;
