Sing unto the LORD, O ye saints of his, and give thanks at the remembrance of his holiness. Psalm 30:4.
King David wrote Psalm 30 at the dedication of his house, which is mentioned in 2 Samuel 5. He had already reigned in Hebron for over seven years before the elders of Israel came to him.
So all the elders of Israel came to the king to Hebron; and king David made a league with them in Hebron before the LORD: and they anointed David king over Israel. 2 Samuel 5:3.
However, it was not until he captured Mount Zion from the Jebusites that he choose the stronghold of Zion for his house, and this stronghold came to be known as the city of David.
Then Hiram, king of Tyre sent craftsman and materials to build David a house. And David perceived that the LORD had established him king over Israel, and that he had exalted his kingdom for his people Israel’s sake. 2 Sam 5:12.
David now had more that just the acceptance of all Israel, but the recognition of the mighty king of Phoenicia.
Rejoice in the LORD, you righteous; and give thanks at the remembrance of his holiness. Psalm 97:12.
We enjoy a direct experience of the holiness of the Lord by His everlasting remembrance of us, described in this Psalm.
You that love the LORD, hate evil: He preserves the souls of his saints; he delivers them out of the hand of the wicked. Light is sown for the righteous, and gladness for the upright in heart. Psalm 97:10 & 11.
How do we come to know that we serve a Holy God? Because He is Faithful to His Word.
I will worship toward thy holy temple, and praise thy name for thy loving-kindness and for thy truth: for thou hast magnified thy word above all thy name. Psalm 138:2.
Peter teaches on remembrance in the opening of his second letter.
I will endeavor that you may be able after my exodus to have these things always in remembrance. 2 Peter 1:15.
When Peter says “I will endeavor”, he is actually using a word for the third time, but the previous two are translated diligence. The root of the word means to make haste, and is the opposite of procrastination. He is saying “add to your faith”, and do it now, today, all day, and every day.
And beside this giving all diligence, add to your faith virtue and to virtue knowledge and to knowledge temperance and to temperance patience, and to patience godliness, and to godliness brotherly kindness and to brotherly kindness charity (agape, aka love). 2 Peter 1:5-7.
Jesus admonishes the church to love one another, to not forget their first love, even as the apostle John wrote:
No man has seen God at any time. If we love one another, God abides in us and His love is perfected in us. 1 John 4:12.
If someone says “I love God” (or “I love Jesus”) and hates his brother is a liar for he that loves not his brother whom he has seen, how can he love God whom he has not seen. And this commandment have we from Him, that he who loves God love his brother also. 1 John 4:20, 21.
Jesus said in John chapter 3; “Truly you must be born again.” This expresses the importance of this doctrine. Now add to this statement the words of Peter:
Seeing you have purified your souls in obeying the truth through the Spirit unto unfeigned love of the brethren, see that you love one another with a pure heart fervently. Being born again, not of corruptible seed but of incorruptible, by the word of God which lives and abides forever. 1 Peter 1:22,23.
We should be overwhelmed by the realization that we must have an unfeigned love, a fervent love; and a pure heart. It is also quite evident to anyone who reads this passage that this is the work of the Holy Spirit accomplished only by obedience. This commitment is attained by diligently adding to our faith unto brotherly kindness, and then agape love.
The other word that Peter uses three times in the passage of his second letter and is clearly emphasized; is remembrance.
Wherefore I will not be negligent to put you always in remembrance of these things though you know them and be established in the present truth. Yea, I think it meet as long as I am in this tabernacle to stir you up by putting you in remembrance. 2 Peter 1:12 & 13.
I now remind you that a remembrance ultimately is God working in us by the power of the Holy Spirit unto “an unfeigned love of the brethren.”
