Once there was this guy.........
He believed in the idea that God directs our eyes (and He does, of course, at times) to what He wants us to know from His Word, and that he could flip open his Bible indiscriminately at random, and plop his finger down, and whatever Scripture was under his finger, THAT was Gods message to him that day.
So, as was his belief, he did so, and the Scripture under his finger said, "...and Judas went out and hanged himself."
SLAM!! He closed his Bible, stunned at what he had read!
"Can't be," he thought, "must've been some sort of fluke; let me try again."
So he flipped open his Bible a second time, and plopped his finger down wherever it landed, and the passage read, ".....go thou and do likewise."
The question is not, "is it a lack of faith" to use Bible software?"
The question is, Will we study Gods Word with a software that is credible, reliable, and well supported by the Bible itself.
Context is one of the most important aspects to Bible study. Any good "software" will help you search the Scriptures to see how it proves itself out, throughout.
You are going to get a number of recommendations about what "software" is best. I like E-Sword, mostly because it is free, but also because I have found it to be packed full of cross-referencing and useful tools.
As to the Spiritual side of using "software," .......God uses Doctors (does He not?) to heal our bodies when we need them. Should we be so stuck on the idea that God can heal, that we wouldn't make use of a trained Physician for our ills? I would suggest to you that "software" that has been written, and can be used to help us, is worth using. God is not offended by our creativity........He GAVE us (mankind) our "creativity," to use in productive and God-honoring ways.
