Start by reading the verse and praying about it. Then write it down on a 3 x 5 card and carry it with you or keep it in your car. Look at it as often as possible and repeat it whenever you can. Pick an accountability person to say it to at the end of the week. Make sure the person is responsible to actually hold you accountable. If you are so inclined please leave me a comment about how you memorize Scripture and what way works best for you.
Blessed are they who keep his statutes
and seek him with all their heart.
(New International Version)
How blessed are those who observe His testimonies,
Who seek Him with all their heart.
(New American Standard Bible)
Blessed are they that keep his testimonies,
and that seek him with the whole heart.
(King James Version)
Blessed are those who keep His testimonies,
Who seek Him with the whole heart!
(New King James Version)
