Jesus Christ offers us in this word a unique reward, he will assume our defense forever, which guarantees that we will live forever.
They are words of encouragement (like all the rest of the Bible) and an invitation to continue fighting until the end. So said the same that would be, but not to fear, to continue that he would return, that he would die, but that he would be resurrected. The apostle Paul also said; "I continue the goal" (Philippians 3:14) "I have fought the good fight, I have finished the race, I have kept the faith" (2 Timothy 4: 7). All these verses refer to the struggles we experience every day, and he urges us to keep going, until we win! With our eyes on our Lord Jesus Christ.
This gives a guarantee that we can achieve it, which is not impossible, if we do it in accordance with his word. Therefore, with that certainty, no one should faint, because if not, his name will be erased from the book of life.
We often feel that spiritual lethargy threatens our Christian life, surely you have also felt at some point the temptation to abandon the battle of faith. Above all, when things do not go well, when finances fail, when children rebel, when we have an argument with our wife (or) about anything, when we unexpectedly lose a loved one or suffer an unexpected illness, it seems to us that God It does not do anything, sometimes the battle is too big.
Many times we feel that we do not have the strength to stand up in the struggle of the Christian life, coming to believe that it is better to live the past life of the old man. But the word of God commands us to fight, remember that victory is already assured, our struggle today must be first with ourselves and our thoughts.
Perhaps the enemy tries to convince us with words like these: "Do not bother to fight, if you fit yesterday in that temptation, you will probably fall today too". "With that sin that you committed today, perhaps your commander Jesus, condemns you to the execution". These accusations are intended to incite us to leave the battlefield. But remember that our General, Jesus, has promised to fight our battles.
He has already defeated Satan and the world, Perseveremos! And win and we will not be erased! Jesus exclaims with us "Vencimos!"
God bless you greatly.
