As First Corinthians states, the first Adam ...and the last Adam (being Jesus). And as Jesus was not the last man ...what is it referring to??

As I listed before (whether in this discourse, or another), several verses in the New Testament of the Bible mention 'sons of God', referring to believers.  Adam was placed in the Garden of Eden, and he was a believer.  His sin did not negate that fact. Yet, his sin followed in line ...until there was One who did not sin.  Of course, we know that reference is only true of Jesus.

Sin is a thing that is much talked about ...and it is defined in a wide range of ways. It is not limited to a failure to follow the Ten Commandments, though many times people focus on those as joining the dialogue as being able to discuss what is assuredly ...sin.

Jesus said, "You shall love the Lord your God with all your heart, and with all your soul, and with all your mind. This is the first great commandment. And the second is like unto it: You shall love your neighbor as yourself."

God loves everyone, and wants us to treat others as we would like to be treated ...some people refer to this as the Golden Rule. Jesus told the story about the Good Samaritan.  God tells us that to know love, we must know Him.  And love isn't selective.  We can pick and choose who we romance ...but we are to love all, and to treat them as we feel we would want to be treated.  

Those who are missionaries don't usually use a 'fire and brimstone' delivery to a people who've never heard of God's love. We may expect more out of ourselves and fellow Christians ...but, the advantage of missionaries is that they don't have to dwell on the specifics of sin, as most of the so-called uncivilized people already have some concept of right and wrong, and know they've spent too much time in the latter.

On the other hand, a supposed more civilized society has often convinced themselves that they have a more in depth understanding of the quality of life ...and seem to be quite adept in changing the definition for themselves, while telling others that they need to focus more on being compassionate to the other person.

Sin is basically separating from God ...and people who don't know God, would find it confusing to think they are separating from our God whom they don't know that much about.

So, we should begin with the love that is easier to understand ...not telling them a lie, as not to offend them, but to tell them of the love of God. And we tell them of how our sin does not have to condemn us ...because Jesus died for us, in our stead.

We who have read more, realize that not only is sin separation from God ...but, sin is death.

And Jesus is life.

We all sin ...and any sane person knows they sin, but not everyone knows Jesus.
