'Permanently' in the Bible

As for you, the anointing [the special gift, the preparation] which you received from Him remains [permanently] in you, and you have no need for anyone to teach you. But just as His anointing teaches you [giving you insight through the presence of the Holy Spirit] about all things, and is true and is not a lie, and just as His anointing has taught you, you must remain in Him [being rooted in Him, knit to Him].

Now, little children (believers, dear ones), remain in Him [with unwavering faith], so that when He appears [at His return], we may have [perfect] confidence and not be ashamed and shrink away from Him at His coming.

No one who is born of God [deliberately, knowingly, and habitually] practices sin, because God’s seed [His principle of life, the essence of His righteous character] remains [permanently] in him [who is born again—who is reborn from above—spiritually transformed, renewed, and set apart for His purpose]; and he [who is born again] cannot habitually [live a life characterized by] sin, because he is born of God and longs to please Him.
