The sword in this painting represents Jesus, the word of God.
The fire emanating out of it shows the strength and authority of the power in God’s word.
It can break through anything; Any hardships, any struggles.

(Ephesians 6:17)
“Take the helmet of salvation, and the sword of the Spirit, 
which is the word of God.”

(Hebrews 4:12) 
“For the word of God is quick, and powerful, and sharper than any two edged sword.”
