"Since we have gifts that differ according to the grace given to us, each of us is to exercise them accordingly..."
I use an online concordance (biblestudytools.com) constantly. I love the online access, too, because it’s right here on my computer while I’m working on my blog. It has a built-in feature to look up the meaning of the original greek and hebrew words, and see where else those words are used in the Bible. This can really shed light on something you're studying, and can even change or give a deeper meaning to a passage!
I am incredibly thankful God gifted certain people with the passion to index and organize so we have things like concordances at our fingertips. The better we understand His Word, the better we can know and nurture our relationship with Christ!
