In writing to a group of Christians who were on the verge of turning from Christ and drifting away into disobedience, the writer of Hebrews urged his readers to not neglect “so great a salvation” (Heb. 2:1-4). Contemplate that for just a moment. What is “so great” about “salvation”?
Salvation is 
“so great” because it is given by a great God, purchased by a great Savior, paid for with a great price, saves from great sins, rescues from great dangers, guarantees great rewards, etc. What else can you think of? Salvation is “so great” because it is the result of great love, great grace, great mercy, great longsuffering, great compassion, great wisdom, great power, etc. What else comes to mind? Salvation is “so great” because it will save anyone, from anything, at anytime, at anyplace, when they will come to the Lord “according to His will.”
Think about the question: “How shall we escape if we neglect so great a salvation?” Don’t neglect the “so great a salvation” that is yours in Christ! There’s nothing greater!
