I second Joshua's recommendation. Accordance is a great program and very powerful for working with Scripture when it comes to searches, word studies, etc. The current Logos for Mac is more of a reader than anything else.

"Although the fig tree shall not blossom, neither shall fruit be in the vines; the labour of the olive shall fail, and the fields shall yield no meat; the flock shall be cut off from the fold, and there shall be no herd in the stalls: Yet I will rejoice in the LORD, I will joy in the God of my salvation." (Habakkuk 3:17-18)
