So you believe, but do you obey?
BQ: So you believe, but do you obey in what you do? This is important to consider.

Q: How much obedience do you show to God? Do you rely on your belief? Is your belief enough without good obedience? When is belief enough?

A:  We'll start off with James 2. "What use is it, my brethren, if someone says he has faith but he has no works? Can that faith save him?" (14) You believe that God is one. You do well; the demons also believe, and shudder. (19) You see that a man is justified by works and not by faith alone. (24) For just as the body without the spirit is dead, so also faith without works is dead. (26)"

"As He spoke these things, many came to believe in Him. So Jesus was saying to those Jews who had believed Him, “If you continue in My word, THEN you are truly disciples of Mine." (John 8:30-31)
The people believed in Jesus, but they had to do more than just that. They had to continue in His word. 

Faith is a necessary foundation. Now that we have the rock and have the foundation laid, let's build something wondrous that leads to eternal life.
