Sin displays it’s poisonous head where God is loved and most adored.
If we live a life of faith on the Son of God, then we shall assuredly live a life of holiness. The implication and consequence of the pursuit of Christ is holiness. But where faith is not exercised unholiness is the consequence. It is through faith that God purifies and cleanses the heart of the Christian and sets him/her apart to his service away from any worldly entanglement. Oh dear Christian, listen, the same faith that brought your justification is still the same faith that sanctifies you. Read Hebrews 11.
Looking to and knowing Christ is the aim, and there is no other way.
