Connection restored
Consider a fruit tree like the one described above. If you break a branch off, it's no longer connected to its source of life. So, how can it produce fruit?
You are like that branch.
Your sin disconnects you from God, your source.
And that's where Jesus comes in, healing that connection.
As the image of God, Jesus Christ came as a man, lived a righteous life, then died to pay the penalty for our unrighteousness.
