Sometimes it's hard to say. He likes to teach me many things at once, which can be rather confusing to summarize into just a few points. I want to make record of this though. I believe that it's important to remember where you cam from and what you learned there so God doesn't have to take you through it again and relearn everything.
Quiet Time makes all of the difference.
When I take the time to meet with God first thing in the morning, I am blessed throughout the day. Reading through the Bible, I am filled with wisdom. When comfy covers get the best of me, and I have to rush to get to school without doing my devotions, the day is hectic and stressful. Of all the things I want to learn permanently, it's this: devotions in the morning = a brighter day.
Be the Change you want to see.
You can tell people what you want them to change about themselves, and they will be offended and ignore you. If you talk about changes in your own life, and actually make those changes, others will follow your example. The Holy Spirit uses your positive example to convict other believers.
Don't Settle for who you are.
Sometimes it can be easy to say, "this is who I am, and it's not going to change." The problem is, this is a self-fulfilling prophecy. If I don't believe that I will ever change, then I won't. The inverse of this is, of course, when I determine that I will change, God is showing me that I can. As long as that change is within His will, my life is blessed by my obedience in having "a teachable spirit."
The Great Commission is not an option.
The last chapter of Matthew is one often overlooked by modern churches, or at best, considered an interesting and inspirational speech to a couple of apostles. This couldn't be further from the truth. Jesus calls us to "go and make disciples of all nations," and He doesn't say "please." God is showing me that regardless of whether or not I feel equipped for witnessing to others, I am. The Holy Spirit has been in me since the moment I was saved. At that moment, I received everything that I need to witness. Convicting hearts is the Holy Spirit's job. Saving people is Jesus' job. Carrying the Good News to the world? That's our part.
