Remember

As he was scattering the seed, some fell along the path, and the birds came and ate it up -- Matthew 13:4 NIV

The enemy will try to steal the knowledge God has given you. Don't let him.

Write

Take a journal to church services to write notes. Keep a notebook by where you commonly pray. Setup a space for a notes app on your phone. Anywhere God may speak to you have a way to write it down. When a thought is given to you, write it down immediately. Don't think you will remember it in a few hours, or even minutes. Capture and hold on to it. Many times I've told myself I would remember what was said, but I forgot. Treat every word from the Lord as precious. Even if you don't know if the thought is from Him, write it down and pray about it.

Endeavor to write something down every day. If you have paragraphs of profound revelation to write, or even if you just write down a few simple words, you aren't sure are significant. Don't put pressure on yourself for what you write, rather than you do.

Form a habit of writing about the things of God.

Review

Review what you have written frequently. Remember what God has said or done. If it was important enough for him to speak, it's important to write down. And, it's important enough to review.

It can help to set a schedule to review, as a guideline. You could endeavor to review Sunday sermon notes on Tuesdays. On Saturdays, you could review the prior week's journal entries.

There is nothing wrong with randomly flipping to an old page and reading it. In fact, you should do that from time to time. But, don't let that be all you do. Have a plan that works for you and do your best to follow it.

Memorize

Take the helmet of salvation and the sword of the Spirit, which is the word of God. -- Ephesians 6:17

Make a daily habit of memorizing scripture. It is called the "sword of the Spirit." Your enemy is real; he is seeking whom he may devour. Don't leave your weapons behind.

These commandments that I give you today are to be on your hearts. Impress them on your children. Talk about them when you sit at home and when you walk along the road, when you lie down and when you get up. Tie them as symbols on your hands and bind them on your foreheads. Write them on the doorframes of your houses and on your gates. -- Deuteronomy 6:6-9

One helpful way of doing this, that isn't hard, is to set up a schedule. Every week learn a new verse, and recite from memory the verse from the week before. You'll be learning a two verses at all times and practicing them 14 days in a row, each. Pick a day every week to review the last month's worth of scriptures so that you are reinforcing them. Make flash cards of the scriptures, and pick another day to pull a few randomly from the past and test yourself.

Memorize as much as you feel called to, but if you find yourself feeling like it's too much, prayerfully consider keeping it easy enough that you actually work on memorizing every day.

In summary, remember the Word, remember his promises, and remember his requirements for your life.
