The scriptures are filled with many admonitions to encourage one another, one Christian to another. Hebrews 3:13, 1 Thess 3:3,4:18,5:11,
These verses show a context to the word 'encourage'. We tend to think of it as 'cheer up' but it has more to do with the root 'courage'. Encourage and exhort are pretty much synonyms in the NT. These verses talk about encouraging one another with the Gospel message of hope and the promise of a life with God after the persecutions and trials of this world.

The ancient Jewish Aramaic translation of Genesis 1:1, as found in "Targum Neofiti," which dates before Yeshua was born reads as follows,
"In the beginning, with wisdom (hebrew Khokhmah), the Son and Memra of the LORD…
This is a very interesting and useful tactic in demonstrating the deity of Christ but I wouldn't use it in a first encounter because the overall tactic is to go after the weaker areas first, the ones they don't have all their defenses up for. Go around the Maginot Line, as it were. Still, this is a very important tool in the arsenal of defending the deity of Christ thanks to Greg Koukl.
