"Tetelestai" is a song for Christians of all ages. It talks about the finished work of Christ on the cross which bought us our salvation. It is not just a beautiful composition to admire or a nice song to enjoy but more so, a declaration of faith to make and assimilate. I say, 'the package of words and works of Jesus is a whole law which can be activated and benefited from through faith.' So, as you sing along, believe that when Jesus says in JOHN 19:30 that IT IS FINISHED, it means He has already and eternally completed the work concerning your salvation, wellbeing, healing, prosperity, peace, etc. Declare it and it shall so be. Tetelestai! It is finished.
