Blue Letter Bible
I have links to 2 bible sites on my sidebar. The first, Bible Gateway is probably the better known one, and is great for getting bible passages in any of a wide range of translations (etc.) and searching for words and phrases. The second is Blue Letter Bible, and has its own strengths that make it worth using as well.
I use Blue Bible for looking up Greek and Hebrew words. I have no formal theological training, and find the site useful for some basic word exploration.
For example, in 1 Cor 7:7 the Greek word for gift is charisma. If I search for ‘1 Cor 7′ and then click on the ‘C’ next to v7, I get this page, with the Greek words and Stron’g numbers for each word or phrase alongside the English from the KJV. If I click on the Strong’s number next to ‘gift’ I get this page, which provides the lexicon entry for charisma. From the usage list I see the various ways in which the word is used, such as Spiritual gift as definition 5. Of course I don’t have to take their word for it, I can check all the references and see, for example, its use to refer to the gift of eternal life in Rom 3:26, and Paul’s delivery from death in 2 Cor 1:11.
On my pda I have MyBible from Laridian, and they have a new concordance that has some of the same features.Technology
