To understand the Bible, you need to grasp the core of the Gospel message, and then interpret everything else by that core message.
This is my summation of what that core is. What do you think? Would you put it differently?
God
Is love,
Complete in Himself,
As Trinity.
He didn’t need us,
Yet
Created all of us
As an overflowing of His love.
Sin
Is our rejection of (His) love,
But eternal life
With Him
Is ours already,
Because Jesus
Enfleshed,
Died,
And rose,
To destroy death’s hold on us.
