Psalm 119:165
Great peace have they which love thy law: and nothing shall offend them.
Psalm 18:18-22
18
They prevented me in the day of my calamity: but the LORD was my stay.
19
He brought me forth also into a large place; he delivered me, because he delighted in me.
20
The LORD rewarded me according to my righteousness; according to the cleanness of my hands hath he recompensed me.
21
For I have kept the ways of the LORD, and have not wickedly departed from my God.
22
For all his judgments were before me, and I did not put away his statutes from me.
1 John 3:19-24
19
And hereby we know that we are of the truth, and shall assure our hearts before him.
20
For if our heart condemn us, God is greater than our heart, and knoweth all things.
21
Beloved, if our heart condemn us not, then have we confidence toward God.
22
And whatsoever we ask, we receive of him, because we keep his commandments, and do those things that are pleasing in his sight.
23
And this is his commandment, That we should believe on the name of his Son Jesus Christ, and love one another, as he gave us commandment.
24
And he that keepeth his commandments dwelleth in him, and he in him. And hereby we know that he abideth in us, by the Spirit which he hath given us.
