The sin condition of the heart entered the world through one man (Adam). This form of the word for “sin” is a noun in the Greek and appears nearly four times more often than the verb in the New Testament. Death entered through this “sin condition” and it spread to all men, because the noun would lead to sinful actions, since all have sinned (verb). Jesus came to destroy and take away the sin of the world, the condition that resulted in everyone being identified as sinners, as inherited through Adam. Through one sacrifice at the cross, God dealt with and resolved the sin problem forever; both the sinful nature and the sinful actions. If this was not the case, Jesus would need to keep suffering repeatedly, and the cross would have to be considered inadequate. Fortunately for us, His one-time shedding of blood was more than enough, and now the issue is simply choosing to believe in order to receive the new nature of righteousness within our hearts.
