John 14:15 "If ye love me, keep my commandments."
We should make it a point to practice what we hear preached. To me...if the Man of God preaches it and he is preaching what God says in His Word that we should be doing then we should not question it...we should just obey!! And if you have a problem with obeying what God says just from what you have heard preached...then study it out for yourself. I know that in my Christian life there have been times that I didn't like what I was hearing that I should be doing according to the Word of God but I also love the Lord enough to want to obey Him. When God dealt with me about changing my way of dress...my flesh didn't like it but I knew it was right. (To read my testimony on this issue you can go here). God had said it in His Word. It took a man of God preaching it and showing me from God's Word what God had to say about it for me to realize that I needed to do what it said. And that is only one area that I am giving example of. There have been other areas such as music, television, going to the movies, the words I use when I am talking, etc.
How many times have you heard something preached and the preacher backed it up with Scripture and you said "That isn't for me" when in reality if it is in the Word of God then it is for you!! God is not a respecter of persons. He expects all His children to obey His commandments. He does not say "If you want to then you can" or "If you are a preacher you must obey my commandments". To me that says that if you love Him you will obey WHATEVER He says in His Word. Whether you agree or not is not the issue. To me if God says it then that settles it!! Nothing else has to be said about it. I want to be as close to Him as I possibly can be. And I want to honor and glorify Him in everything I do and everything I say. So...as for me...I'm going to obey His commandments as best I can with His help. And don't think you will always know everything there is to know about living for God. I have been saved for going on 13 years and I'm still learning.
So don't be afraid to say "Yes Lord...I will do it". That is what He wants from us anyway...a willing and obedient heart.
