The way of the gospel is not as easy as living a normal life doing what we want, the way of the gospel implies many things, the main one of all is to deny ourselves, what we like, and many times our dreams, because of this way we teach the world that we have nothing to do with this temporary place, but we are looking for a celestial city, whose architect is God.
We were called not just to occupy another place in the church, but we were called to remain in God, in His teachings, to live them and in this way be firm for those difficult moments in the Christian life. It is not like many people today paint a modern gospel, but it is about the gospel of the cross, dear brothers, to suffer for Him and live for Him.
27 As for you, the anointing you received from him remains in you, and you do not need anyone to teach you. But as his anointing teaches you about all things and as that anointing is real, not counterfeit—just as it has taught you, remain in him.
28 And now, dear children, continue in him, so that when he appears we may be confident and unashamed before him at his coming.
29 If you know that he is righteous, you know that everyone who does what is right has been born of him.
1 John 2:27-29
Biblical doctrine is an essential part of the Christian life and precisely this is what the apostle tells us in these verses. The way we stay in God is by keeping His Word, but for us to be able to keep it we have to study it.
