This is the month of Elul and traditionally also called Teshuva, the season of repentance, in the Hebrew world. I believe it is a great time for all of us to take a deep look into our own hearts and lives to see what sins we are harboring there.
What is the definition of sin? Here it is straight from one of the original followers of our Messiah:
1 John 3:4
Everyone that practices sin also practices lawlessness; and sin is lawlessness
What is lawlessness?
So in summary:
Sin, according to Scripture (that was written after the Resurrection and after Paul) is the disregard for and/or the violation of God’s Law, the Torah.
With that in mind, please watch the below video, with a humble and teachable heart.
