Look at a variety of Scripture memory programs and then pick one that you believe will work for you (the Memorization Resource page is a good place to start).
Most people find memorizing Scripture to be difficult at first (it gets easier with practice), so some determination is helpful.
Start small. Pick a few verses or a short passage and give yourself plenty of time to complete your memory goal. It is more useful to start small, succeed, and see the impact of the memorized Scripture in your life than to set unrealistic memorization goals, fail, and never try again. The goal isn’t the quantity of Scriptures memorized; the goal is to reflect on your passages and let God’s Word impact your life.
Pray for God’s help in memorizing and in letting his Word change you.
Have a specific time of the day that you will memorize so that it becomes a habit. If you memorize at random times of the day, it is often easy to forget and skip a day, which often results in skipping numerous days.
Memorize your passage word-for-word and also memorize the reference. Memorizing exact wording actually helps you remember longer. Knowing the reference will help you find the verse in the future in case you forget some of what you’re working to memorize.
Review your memory passages every day to keep them on your mind throughout the day and so that over time you will not forget them.
If at all possible, find someone else to memorize Scripture with you. That way, you can push each other to engage more deeply with the verses and keep each other accountable to stick with the program.
