The verses are the power of God working in us. If we believe His Word. If you cant quote the Word from inside yourself, you cant walk after the Holy Spirit.
The verses are not the power of God, but the power of God is shown in us as we are obedient to His commands and statues we read of in His written word.
Deuteronomy 6:1 Now these
are the commandments, the statutes, and the judgments, which the LORD your God commanded to teach you, that ye might do
them in the land whither ye go to possess it: 2 That thou mightest fear the LORD thy God, to keep all his statutes and his commandments, which I command thee, thou, and thy son, and thy son's son, all the days of thy life; and that thy days may be prolonged.
Deuteronomy 10:12 And now, Israel, what doth the LORD thy God require of thee, but to fear the LORD thy God, to walk in all his ways, and to love him, and to serve the LORD thy God with all thy heart and with all thy soul, 13 To keep the commandments of the LORD, and his statutes, which I command thee this day for thy good?
Read Deuteronomy chapter 27 and 28 as you will understand why God will either curse or bless us.
