'Great Things' in the Bible

Thy righteousness, O God, is very high, and great things are they that thou hast done; O God, who is like unto thee?

They forgot God their Savior, which had done so great things in Egypt,

Then was our mouth filled with laughter, and our tongue with joy. Then said they among the heathen, "The LORD hath done great things for them."

Yea the LORD hath done great things for us already, whereof we rejoice.
