Having Assurance

‘For the which cause I also suffer these things: nevertheless I am not ashamed:  for I know whom I have believed, and am persuaded that he is able to keep that which I have committed unto him against that day.’—2 Timothy 1:12‘And if we know that he hear us, whatsoever we ask, we know that we have the petitions that we desired of him.’—1 John 5:15‘And we know that we are of God, and the whole world lieth in wickedness.’—1 John 5:19
