Memorizing the Bible - one of things in life that really is important.
It takes time...sure... but time WELL spent. Time learning more of God's word...implanting it into your life... it's the word of God...our daily bread... and the more we memorize, the more we learn. The more in situations...we can be able to say, "Oh! I know a great verse that applies with this!"
It's a constant thing you have to do... you can't just memorize a few verses one day, then the next day, give up and forget everything.
It's a daily thing. Constantly quoting scripture. Constantly reading it. Constantly learning more about God.
Memorizing the Bible IS important. It's very important.
The Bible says to always be ready to give an answer to those who ask (1 Peter 3:15, "Always be prepared to give an answer to everyone who asks you to give the reason for the hope that you have). And how else can we do that then by KNOWING God's word?
...Take the time to learn God's word.
