For this reason we must pay much closer attention to what we have heard, so that we do not drift away from it.
Hebrews 2:1 NASB
This warning is not given to the unsaved. It is given to those who know Christ, those who are blood bought and redeemed. It is a very real possibility to drift away. We are exhorted to give heed to the word of God. We must pay attention to it and allow it to shape our lives. We must be diligent to put it into practice. It is my belief that a christian does not just get up some day and decide to fall away. It is a drifting away over time, gradually growing comlacent, content with our salvation, comfortable, feeling safe, letting down our guard. We can get careless about obedience, we can get lazy about prayer, and time in the word. We will soon forget the truth and fall into deception.
How will we escape if we neglect so great a salvation (verse 3)? We neglect our salvation at our own peril. We live in a world that bombards us with every imaginable temptation. Deception abounds. It is the overcomer, the one who endures to the end (Matt 24:13) that will be saved. For we have become partakers of Christ if we hold fast the beginning of our assurance firm until the end (Heb 3:14).
The good news is this "Greater is He that is in you, than he who is in the world" (1John 4:4).
