Jesus was nailed to the Cross with 3 nails - two on His hands and one through both feet.
The nails represent the three main areas of sin in our lives - the lust of the flesh, the lust of the eyes and the pride of life.
When He died on the Cross, those areas of sin no longer has power over us. His death has given us victory over the flesh (lust of flesh), the world(lust of eyes) and the devil(pride of life).
We can overcome their tempting presence by claiming and proclaiming Jesus is the Way, the Truth and the Life.
Jesus is the Way of God (not the way of the flesh)
Jesus is the Truth of God (not the 'truth' of the world and all that entice our eyes)
Jesus is the Life of God (true Christ-centred life and not the worldly self-centred life)
