For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms.

Eph. 6:12 NIV

Invicta means unvanquished.

Jesus came to earth as God clothed in humanity to save us from our sin (Matthew 1:21), to heal us (Luke 5:31) and destroy the work of the devil (1 John 3:8).

And this work of the devil has always been to steal, kill and destroy every good blessing that God has planned for us, His children.

Jesus also came to give power and authority over Satan to those who would have faith in Him. In His name we are to preach the Gospel, heal the sick and cast out demons (Mark 16).

And time after time in the Bible, Jesus demonstrated this authority and power over the forces of darkness.  We see how He was victorious over temptation, never fell to sin and always overcame the enemy. From the first demon He cast out in Capernaum, to His Temptation in the Wilderness, to the Resurrection, Jesus was victorious over Satan—every single time.

You can rightly say that Jesus Christ, the Son of the Living God, was, is and always will be—unvanquished.
