Хочу прочитать Библию на английском. Какую версию посоветуете?

Версию (перевод) логичнее выбирать в зависимости от вашего уровня понимания английского языка. Вернее, от возможности понимать англоязычный текст.

Есть библейские переводы, выполненные на простой английский язык с использованием  минимального словарного запаса. [New Life Version, God's Word Translation]

Есть переводы-пересказы, которые тоже представляют собой простые тексты. [The Living Bible, Good News Bible, Contemporary English Version, EasyEnglish Bible. Если вы выберете Easy-to-Read Version, то можете читать его вместе с русским изданием "Библия. Современный перевод", которая переведена с этой английской версии.]

Есть даже перевод, в котором сложные слова имеют по несколько синонимов - Amplified Bible.

Не советую читать King James Version (т.н. "Перевод короля Иакова"). Этот текст не всегда адекватно понимают даже многие англоязычные люди, особенно те, чей английский язык -- второй. Он наполнен устаревшими словами и лишь запутает. 

Есть переводы, выполненные на современном английском языке. Есть переводы, сделанные на американской версии английского языка. Если уровень понимания английского текста хороший, то можно порекомендовать: New International Version, New American Standard Bible, New Revised Standard Bible with The Apocrypha, New Jerusalem Bible.

Сейчас в России можно купить Библию (и Новый Завет) с параллельными англо-русскими текстами. Это иногда может помочь понять английский перевод, но может и запутать -- русский и английский тексты переводились, как правило, с различных "оригиналов". 

Я нашёл в интернете пример перевода одного библейского отрывка (Ин. 3:16-17) в разных англоязычных версиях. Думаю, вы сможете сами составить своё мнение о понимании того или иного перевода.
