Christ also said that they who believe on Him will do the works and miracles He did, and even greater ones (John 14:12).
Is that symbolic?
John 14:12 Verily, verily, I say unto you, He that believeth on me, the works that I do shall he do also; and greater works than these shall he do; because I go unto my Father.
I view Christ's Word as truth. This means we are all lacking in faith today. We are all double minded due to our carnal desires.
This is truth, I do not make up excuses to nullify the Lords Word.
Pray without ceasing to me means to pray every day or at least regularly.
