Devotion...

"And they devoted themselves to the apostles’ teaching and the fellowship, to the breaking of bread and the prayers. And awe came upon every soul, and many wonders and signs were being done through the apostles." - Acts 2:42-43

I owned an ant farm when I was a kid. It was a great study of true devotion to a cause. These little guys were all about building tunnels and feeding the family. They never gave up, no matter how many times the "farm" fell over and destroyed their good work. The words of Solomon were on point when he wrote in Proverbs 6:6, "Go to the ant, O sluggard; consider her ways, and be wise."
The early believers were "devoted" to spiritual disciplines and God blessed with great power. The word for "devoted" speaks of endurance or steadfast faithfulness. No matter what happened to deter the people of God, they pressed on day by day with tenacious determination, just like the ant. Persecution came in waves, but perseverance brought divine wonders.
Stay the course my friend. With "devotion" to the cause of Christ will come awesome results. Such steadfastness will require an endurance that only God can provide, but He is able  "... to do far more abundantly than all that we ask or think, according to the power at work within us." (Ephesians 3:20) When your tunnels cave in, just build new ones and press on with renewed devotion.
