For our struggle is not against flesh and blood, but against the rulers, against the powers, against the world forces of this darkness, against the spiritual forces of wickedness in the heavenly places. (Ephesians 6:12)
If you are a Christian, you are in a spiritual war and you had better be prepared for the battles ahead. The enemy is not other humans. The enemy is Satan, his demonic forces and the worldly false doctrines promoted by those who have been deceived by Satan's lies and schemes; ...so that no advantage would be taken of us by Satan, for we are not ignorant of his schemes. (2 Corinthians 2:11)
Don't be afraid to engage this enemy. You are already victorious because Jesus Christ, who is in you, has already defeated Satan at the cross;
You are from God, little children, and have overcome them; because greater is He that is in you than he who is in the world. (1 John 4:4)
Just be sure to put on and leave on the full armor of God (see Ephesians 6:10-17); Finally, be strong in the Lord and in the strength of His might. (Ephesians 6:10) Fight on Christian soldier and Maranatha!
