Our Scripture reading today is Ephesians 6:12, "For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places."
The spiritual battle that we face every day is not against who or what we can see. There are very strong forces that are invisible to us who are are seeking to discourage, defeat, and destroy everyone in their path. Thankfully, we can overcome any and all spiritual foes in and with the power of God. God's Spirit dwells within us and will enable us win whatever battle we are facing. 1 John 4:4, "Ye are of God, little children, and have overcome them: because greater is he that is in you, than he that is in the world." Zechariah 4:6, "Then he answered and spake unto me, saying, This is the word of the LORD unto Zerubbabel, saying, Not by might, nor by power, but by my spirit, saith the LORD of hosts."
This is why it is so important that we are filled with the Spirit every day!
