“...because Judas was in charge of the money...”(John 13:29)

Although Judas had been around the Lord from the onset of His ministry, it  appears he had not bought into the vision. He may have been thrilled  at the onset by this novel concept of a kingdom that this young charismatic Jew was pushing. Any Jew of his day would have welcomed the prospect of a kingdom that would free them from the 'uncircumcized' Romans.  Because their ancestors had been freed from the Egyptians in the same way.  So he must have eagerly anticipated their deliverance. However, after following his new master for a couple of months, a year, and then two, Judas soon discovered that his hopes would not be fulfilled. The messages Jesus was teaching were not what he had hoped to hear. They were not the words of a revolutionist. 

These lectures and the training they were getting would not equip them with the physical prowess required to topple the Roman government and restore their honor and supremacy. Jesus was teaching about loving their enemies and paying taxes to Caesar. Judas, apparently, could not accept such messages. He must have felt betrayed or deceived. His initial enthusiasm gave way to disappointment, then rage, contempt, and finally resentment. He had lost his sense of commitment. So although he was still physically a part of the team, his heart was no longer with them. 

To make things worse, he decided to help himself to the donations that were being received for the ministry. He was, after all, the keeper of the money bag and the treasurer. 

Like Judas, you may be in a marriage or relationship and already feeling frustrated because your expectations are not being met by what you are witnessing or experiencing. Or you are disappointed in the organization or institution that you have sacrificed a lot for and invested a lot of energy into, only to see no real results or rewards.
Hope deferred makes the heart sick, the Scriptures tell us. 
For many, this can lead to discouragement and a total loss of commitment. However, true commitment is a willful act. It exceeds feelings, and is more than expectations.  It is a choice: a choice to be present to carry out the decisions you had initially decided upon.  It is a choice to keep  loving, trusting and obeying the Lord even when it seems like what you were expecting does not seem to be coming to pass.
