Response to Delrain
I have previously encountered enemies with threats. It helped me to remember to have faith, trust in the power of God, and to not be afraid.
Instead of allowing fearful thoughts to take over my mind, I would say the following: "All of my enemies will be confounded and ashamed," (Psalms 35:4), "No weapons formed against me shall prosper, and every tongue that rises against me in judgment shall be condemned." (Isaiah 54: 17)
Other helpful scriptures are: "With us is the Lord our God to help us, and to fight our battles", (2 Chronicles 32:8)..."You need not to fight in this battle...stand still, and see the salvation of the Lord" (2 Chronicles 20: 17).
And I agree, call the police if necessary, but keep in mind the power of God can cause your adversary's plans to fail.
God be with you, and your family.
