Ingratitude to God is a Sin.
The difference between the lived word and the acknowledged one or Gratefulness and Gratitude: “The purpose of life is not to be happy. It is to be useful, to be honorable, to be compassionate, to have it make some difference that you have lived and lived well.” ― Ralph Waldo Emerson
“It’s the action, not the fruit of the action, that’s important. You have to do the right thing. It may not be in your power, may not be in your time, that there’ll be any fruit. But that doesn’t mean you stop doing the right thing. You may never know what results come from your action. But if you do nothing, there will be no result.”
― Mahatma Gandhi.
Elders said to me, Weep not: behold, the Lion of the tribe of Juda, the Root of David, has prevailed to open the book, and to loose the seven seals thereof.
Paul is urging Timothy to endure for the cause of Christ. He gives Timothy the example of the soldier, who works hard to please his master and the farmer, who works for the reward of the harvest, etc. He then quotes a hymn in verses 11-12 that evidently is doctrinally correct to give Timothy further motivation for enduring. What then is the motivation? We must take the structure into account to determine this.
The second thing to consider is the literary structure of the quote. It is quite common in Hebrew literature to see things arranged around a chiasm. It is possibly the case in this passage. And thus we have the following:
a. For if we died with Him, we shall also live with Him.
b. If we endure, we shall also reign with Him;
b.1 If we deny Him, He also will deny us;
a.1 If we are faithless, He remains faithful; for He cannot deny Himself.
