We Labour till Christ be formed in us & this is called pressing onto perfection that's the image & likeness of Christ. The word labour as a double meaning, firstly labour means to work & we ought to work on ourselves to be a representative sample of Christ by washing the pollutants that operate in our lives with the word of God. Secondly when a lady is about to give birth she goes through a process called labour which is very painful but she is about to bring forth something beautiful & the same with us there's as great burden & expectancy upon us to bring forth something beautiful that's being Christ. That light of the world that dwells in you, let him be shown as an outward expression in your life & whatever happened or going to happen in your life that already as or going to cause you pain, that going to position you to give birth to something beautiful being Christ. Remember this is not a literal birth but a spiritual one for the Christ in us to be shown as a mirror reflection to this dying world,so we could say that truly if you seen me you have seen the father & if you heard me you have heard the father.
