If a marathoner drops out of or breaks away from the official 42.195km course, he will be disqualified whatever the reason may be. In the same manner, Christians who are running towards Heaven also have some official rules to keep. The rules stem from the Word of God. If you resort to the excuses that the world has changed and others do not keep the rules and you choose to live outside of the truth, you will be distanced from the life of blessing and even salvation.
"For this is the love of God, that we keep His commandments; and His commandments are not burdensome" (1 John 5:3).
