I agree with what all have said, and would like to add, that the study of God's Word is so important in this day and age. Well, it always has been. But it is so important today because we live in such a feeling-oriented world. Feelings come and go; experiences are subjective. But God's Word is objective truth and does not change. His Word is a rock upon which we can stand, and we will not be disappointed.
thank you everyone, it's very kind of all of you! It's a slow but very enjoyable process for me: by that I mean, adding new ones, but also reviewing old ones. God is good.
We can compare Psalm 1:3 to John 15:5. (To paraphrase a little, if I may) -- If someone abides in the Vine, Jesus Christ, he or she will produce fruit. If you don't stay in the vine, you will be like a dried up branch (verse 6). He also said in verse 5, "apart from Me you can do nothing" (ESV).
I echo what others have just said, Luke. Having such a website by which to on a daily basis meditate on God's Word has made a huge change in my life. Please know that you are performing a service dear to God's Heart because of how you are blessing His children in this way.
I noticed yesterday something new about the user interface which in my opinion is a nice change: there is now an option to have more practice, even when you score 90% or more on a verse. Previously, that option appeared only if you had scored less than 90%. I'm going to try that out now :) I think that will be very useful, when you come across some verses that you especially want to repeat and focus on. Thanks Luke!
