There is power.

And Jesus cried out again with a loud voice and yielded up his spirit. And behold, the curtain of the temple was torn in two, from top to bottom. And the earth shook, and the rocks were split. The tombs also were opened. And many bodies of the saints who had fallen asleep were raised, and coming out of the tombs after his resurrection they went into the holy city and appeared to many. When the centurion and those who were with him, keeping watch over Jesus, saw the earthquake and what took place, they were filled with awe and said, “Truly this was the Son of God!” (Matthew 27:50-54 ESV)
There is power in the name of Jesus. We can not forget the sacrifice made on the cross for all of us, to cleanse us from our sins and save us from the hell we deserve. But we also can’t forget the power of his resurrection that brings new life in the Spirit to everyone who believes.
