“Therefore let that abide in you which you heard from the beginning. If what you heard from the beginning abides in you, you also will abide in the Son and in the Father. And this is the promise that He has promised us—eternal life. These things I have written to you concerning those who try to deceive you. But the anointing which you have received from Him abides in you, and you do not need that anyone teach you; but as the same anointing teaches you concerning all things, and is true, and is not a lie, and just as it has taught you, you will abide in Him.” 1 John 2:24-27, NKJV
The word abide here means to remain/live/dwell, and, like our bodies, our spirits continuously abide somewhere or in something. For Christians, abide can and should be an action associated with personal sanctification. While our salvation is a free gift and not dependent on works, our living relationship with Christ must be cultivated on a daily basis. We abide in the truth by reading and meditating on the absolute Truth of Scripture, and we abide in Christ by obeying His commands. This is how we demonstrate our love for Him and grow into spiritual maturity!
