Psalm 125
1 They that trust in the LORD shall be as mount Zion,
which cannot be removed, but abideth for ever.
2 As the mountains are round about Jerusalem,
so the LORD is round about his people
from henceforth even for ever.
3 For the rod of the wicked shall not rest upon the lot of the righteous;
lest the righteous put forth their hands unto iniquity.
4 Do good, O LORD, unto those that be good,
and to them that are upright in their hearts.
5 As for such as turn aside unto their crooked ways,
the LORD shall lead them forth with the workers of iniquity: but peace shall be upon Israel.
The warning here is that while the Lord (Jehoah) can be trusted to keep his people from the evil, if they put their hands to iniquity, judgement will fall on them just as it will to the workers of iniquity.
This is very similar to the warning in 1 John 5:18
18 We know that whosoever is born of God sinneth not; but he that is begotten of God keepeth himself, and that wicked one toucheth him not.
There is a keeping yourself, a choice to follow the ways of the Lord. The Lord is a strong tower for those who will run to him. He calls even the workers of iniquity to come and be cleansed; the weary to come and receive rest. He is well able, mighty to save whosoever will.
Prov 18:10 The name of the LORD is a strong tower: the righteous runneth into it, and is safe.
Isa 65:2 I have spread out my hands all the day unto a rebellious people, which walketh in a way that was not good, after their own thoughts; (Rom 10:21)
Matt 11:28 Come unto me, all ye that labour and are heavy laden, and I will give you rest. 29 Take my yoke upon you, and learn of me; for I am meek and lowly in heart: and ye shall find rest unto your souls. 30 For my yoke is easy, and my burden is light.
Take heed to the admonition to repent and believe, Jesus alone can remove your sin.
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: 2 And he is the propitiation for our sins: and not for ours only, but also for the sins of the whole world.
Those he has made righteous can run to him and be safe, and those who have sinned can run to him and receive cleansing as well as safety from the evil.
Gal 1:3 Grace be to you and peace from God the Father, and from our Lord Jesus Christ, 4 Who gave himself for our sins, that he might deliver us from this present evil world, according to the will of God and our Father: 5 To whom be glory for ever and ever. Amen.
