Grace is Gods way of saving us, it is not earned, its a gift. Only if we sin without care, does the lord use chastisement.
But even that is for to teach us right from wrong and to correct us into salvation. What father does not correct his children? If we endure it God treats us as sons, as a loving father
All men have sinned and come short of the glory of God, bad thoughts dont change that. But we should pray always to let God help and speak peace into our hearts. Think on good things as God is greater than our fears.
Sin dwells in us there is nothing we can do about it, but Christ can.
When it comes to sins that bother our mind, Paul give us the answer. O wretched man that i am, who shall deliver me from this body of death. It is Christ who delivers us from sin, or forgives us of it...
1Jn 2:1 My little children, these things write I unto you, that ye sin not. And if any man sin, we have an advocate with the Father, Jesus Christ the righteous:
Rom 7:14 For we know that the law is spiritual: but I am carnal, sold under sin.
Rom 7:15 For that which I do I allow not: for what I would, that do I not; but what I hate, that do I.
Rom 7:16 If then I do that which I would not, I consent unto the law that [it is] good.
Rom 7:17 Now then it is no more I that do it, but sin that dwelleth in me.
Rom 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.
Rom 7:19 For the good that I would I do not: but the evil which I would not, that I do.
Rom 7:20 Now if I do that I would not, it is no more I that do it, but sin that dwelleth in me.
Rom 7:21 I find then a law, that, when I would do good, evil is present with me.
Rom 7:22 For I delight in the law of God after the inward man:
Rom 7:23 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.
Rom 7:24 O wretched man that I am! who shall deliver me from the body of this death?
Rom 7:25 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.
This is not an excuse to go out and sin willingly, this is to show us that we have a sin nature and that God understands it..
We are freely justified by his grace if we have faith in Christ. Then we can let God do the work in us with worship and praise and prayer.
We have peace with God because now we know he's not a fire breathing dragon. Will there be test and trials of our faith, yes. But God does not allow them to over come us, if we hold on to our faith and confidence in Christ.
Rom 3:9 What then? are we better [than they]? No, in no wise: for we have before proved both Jews and Gentiles, that they are all under sin;
Rom 3:10 As it is written, There is none righteous, no, not one:
Rom 3:11 There is none that understandeth, there is none that seeketh after God.
Rom 3:12 They are all gone out of the way, they are together become unprofitable; there is none that doeth good, no, not one.
Rom 3:13 Their throat [is] an open sepulchre; with their tongues they have used deceit; the poison of asps [is] under their lips:
Rom 3:14 Whose mouth [is] full of cursing and bitterness:
Rom 3:15 Their feet [are] swift to shed blood:
Rom 3:16 Destruction and misery [are] in their ways:
Rom 3:17 And the way of peace have they not known:
Rom 3:18 There is no fear of God before their eyes.
Rom 3:19 Now we know that what things soever the law saith, it saith to them who are under the law: that every mouth may be stopped, and all the world may become guilty before God.
Rom 3:20 Therefore by the deeds of the law there shall no flesh be justified in his sight: for by the law [is] the knowledge of sin.
Rom 3:21 But now the righteousness of God without the law is manifested, being witnessed by the law and the prophets;
Rom 3:22 Even the righteousness of God [which is] by faith of Jesus Christ unto all and upon all them that believe: for there is no difference:
Rom 3:23 For all have sinned, and come short of the glory of God;
Rom 3:24 Being justified freely by his grace through the redemption that is in Christ Jesus:
Rom 3:25 Whom God hath set forth [to be] a propitiation through faith in his blood, to declare his righteousness for the remission of sins that are past, through the forbearance of God;
Rom 3:26 To declare, [I say], at this time his righteousness: that he might be just, and the justifier of him which believeth in Jesus.
Rom 3:27 Where [is] boasting then? It is excluded. By what law? of works? Nay: but by the law of faith.
Rom 3:28 Therefore we conclude that a man is justified by faith without the deeds of the law.
Rom 3:29 [Is he] the God of the Jews only? [is he] not also of the Gentiles? Yes, of the Gentiles also:
Rom 3:30 Seeing [it is] one God, which shall justify the circumcision by faith, and uncircumcision through faith.
Rom 3:31 Do we then make void the law through faith? God forbid: yea, we establish the law.
As far as fear, some fear can be a good thing. The fear of God is the beginning of wisdom.
Paul had fears and trouble on every side of his walk with God. But God was with him, he didnt have a worldly fear (ie satanic fear) or spirit of fear, but a natural fear. The wretched man fear...
And i think this is the fear you have, lift up your head and taste and see that the lord is good
2Co 7:5 For, when we were come into Macedonia, our flesh had no rest, but we were troubled on every side; without were fightings, within were fears.
God bless
