It seems like there is so much to learn about God, it can be overwhelming.

Just like meeting someone new, there is a lot you can tell about a person upon introduction. From there it takes a lifetime to go forward into the deep relationship He desires to have with us. It is a process, and thats why it is called a Christian walk. Yes, there are some first steps we all must take, but after that we have much to learn--it's actually a wonderful journey!
For we are his workmanship, created in Christ Jesus unto good works, which God hath before ordained that we should walk in them. (Ephesians 2:10)
