I read Hebrew and Greek. I use both languages all the time in my studies.
That being said, the Bible faithfully translated by human beings in our heart language, is all we need to hear the gospel, and for God to save us, and to grow as a follower of Jesus Christ.
Now, theology is a different matter. In order to exegete the text, you really do need to know the original languages. For one thing, as someone said, verb tenses have different nuances. Rather than time being important in Greek, aspect is. Thus, the Aorist, which we like to think of as past tense, is often used for present tense, and sometimes even future.
Noun cases don't exist in English. At least not spelled out. German has them, and they are virtually identical to Greek. There are many subtleties that come out of this. I remember one passage where an adjective was separated from its noun by 25 words. You can't do that in English. You can in Greek, because the case endings show you the adjective and it's noun.
Consequently, the run on sentences which Paul uses, which are perfectly acceptable in Greek, have to be changed. Subjects have to be thrown forward in English, losing the emphasis if they were thrown back in Greek.
And sometimes, what seems easy and clear in English is tricky in Greek. Some passages it is difficult to translate perfectly. We are not 1st century Greeks or Hebrews, and there are times the cultural implications are lost in translation.
My advice is to find a good, modern version and read it. Don't worry about minute variations. God will speak to you from the Bible. If you start being interested in Greek and Hebrew, take some classes. There are some good on-line classes, now. Don't do concordance theology. I say that, because before I knew the original languages, I came up with some wrong ideas, using only Strong's. A good knowledge of grammar is essential, to exegete the text, and a good vocabulary helps. Greek has been studied to death. You can get flash cards with the highest frequencies, and memorize them. Hebrew also has flash card sets. But if you don't want to study, God will lead you in English!
