When Adam transgressed, he affected and infected all that would come after him. When God created man, He did so after His own likeness (Genesis 1:26; Genesis 5:1), but when Adam bore a son after the fall, the Bible says that Adam “begat a son in his own likeness” (Genesis 5:3). Adam’s sin came with dire consequences experienced by all. All those born of Adam’s seed bear Adam’s image (1 Corinthians 15:47-49) and the Bible points out that “in Adam all die” (1 Corinthians 15:22). At the same time, no man faces the eternal judgment of God for bearing Adam’s image, but he does so based upon his own practice of sin and refusal to accept God’s free gift of salvation through His Son, Jesus Christ.
Imagine the vulnerabilities of a watchman who refuses to keep his eyes open to every possible angle from which danger could arise. No doubt the enemy would scout the land observing the bad habits of the watchman. If the watchman fails to examine each point of entry, the enemy will attack from the unprotected angle. In like manner, believers are to walk circumspectly. The word circumspect means to look all around. Believers are to be sober and vigilant knowing that their enemy, the Devil, “walketh about, seeking whom he may devour” (1 Peter 5:8). God’s enemies always search for the weak spot where the hedge has been cut down or ignored. This is why there is no angle in the believer’s life that can be safely ignored.
