The sacrificial love of God through Christ protects the believing heart from the touch of evil.

Therefore Jesus said again, “Very truly I tell you, I am the gate for the sheep. I am the gate;
whoever enters through me will be saved. They will come in and go out, and find pasture.
The thief comes only to steal and kill and destroy; I have come that they may have life,
and have it to the full.
John 10:7, 9-10, NIV
