The more you trust in God, the more he will make it clear that your victory is caused by him, and remove all possibility for the explanation that it's just a coincidence, or that you're doing it on your own.
When Gideon went up with 30,000 soliders against the Midianite army who had 65,000, God didn't want any of them thinking they would win because of their own skill or strength. So he had Gideon tell the cowards to leave, and there were only 10,000 left. Then God had Gideon tell them to drink at the river, and the ones who rested leisurely next to the river and drank sufficiently, he told them to leave. The rest who ran around and drank hurriedly, ready for battle, God said to Gideon, "that's your army." Only 300 men. There's no human way they could win, but of course they did win.
Jesus fulfilled so many prophecies that there was a 82 x 10^120 chance that anyone could fulfill them all. But of course, he did fulfill them all.
Our God is the God of Unlikeliness.
Samson didn't always need extra strength. But at exactly the time he needed it, it was said that he was filled with the spirit, which meant he didn't have strength, but at the exact moment he needed it, God gave it to him, and for no longer than that.
God does not do anything uselessly. God does not give extra. He gives just enough, to prove that our victory comes from him, and not us.
If one has total trust in God's Divine Providence, he may find himself in a situation where there's no earthly way his needs will be provided for, and then suddenly, at the last second, God will provide. Many of the Saints had exactly this happen to them.
St. John Bosco, about 150 years ago, needed a certain sum of money by a certain day, or everything would be closed down, and had no way of obtaining it. The very day he needed it, a man came in as the Saint was praying, and offered exactly that amount of money as an alms, not knowing about the situation.
About 80 years ago, Venerable Fulton Sheen went on a trip to visit Lourdes in honor of Our Blessed Lady, not having enough money for the hotel or to get back. But he asked her to take care of it. And he chose the best hotel, figuring if she could obtain a miracle, she could obtain a small one just as well as a big one. So he went and stayed for 9 days, just as long as a Novena, and on the last day, at night, when he was beginning to wonder how she would take care of him, as Fulton Sheen was praying in the garden, a man came up and asked him to accompany his family who were touring. He also said, "have you paid your bill?"
And time would fail me to mention similar stories that happened to St. Francis of Assisi, St. Benedict, St. Francis de Sales, St. Theresa of Calcutta, and many others...
Our God is the God of Last Minute Victory, lest anyone think it was his own devising or cunning or planning or scheming that gave themselves the victory.
If a person had trust like these great Saints, they might find themselves in a situation where they're living paycheck to paycheck, with no savings, no retirement fun, no backup plan, only barely enough money for their essential needs of life, and no guarantee of how long the work will last, and yet this lasts for years.
Because God works all things for the good of those who love Him, and God works with those who love Him for the good of all things.
