Is Salvation easy??

Tonight while on my way home from work, the radio station I was listening to brought up a very interesting, controversial topic.  And it just happened to fit perfectly with the book of James study that I am doing right now!
They were discussing Whitney Houston.  Did she go to heaven? Before her death and throughout her life she had professed Jesus as her Lord and Savior.  However, she was in the midst of an addiction. 
DID SHE GO TO HEAVEN???
There were multiple stances taken on the subject. 
Some believed that Salvation was easy.  Meaning, once you accept Jesus into your heart, you WILL go to heaven.  You are saved.  PERIOD.
The others believed that you can actually LOSE your salvation.  By your lifestyle.  By your sin.
One person actually called in and said we had to be PERFECT, you know, WITHOUT sin, to go to heaven.  She then sited the famous Philippians 4:13 verse.  (I don’t care who you are, if you believe that, NOBODY is going to heaven!  Scary.)
So, this topic got my wheels spinning.  Here’s what I believe: 
First of all, we ARE NOT saved by our works, but by the grace of God alone.  With that being said, “…faith by itself, if it is not accompanied by action, is dead.” James 2:17  In our James study with Beth Moore, she basically explains it as “real faith is demonstrative.”  The power in the Holy Spirit “convicts and compels” you.  When you have a relationship with Christ, you WANT to do good deeds.  You WANT to bear fruit.  You WANT the love of the Lord to come out through you onto others.  “Our faith is pumped into our actions…”  I mean, even the devil “believes” in God!
“You see that faith was active together with his works, and by works, faith was perfected.”  James 2:22
Secondly, addiction is a sickness. Coming from a nurses viewpoint, people who struggle with addiction, whether it be drugs or alcohol, are SICK.  People tend to think that, like mental health disorders, because it is “in your brain,” you can overcome it.  This is simply NOT the truth.  It’s like trying to talk yourself out of having diabetes, or not getting chemo for your cancer and just “thinking” yourself to beating it. People with addictions need help.  They need people to love them and help them. They are desperate for Gods mercy.  Can people who struggle with addiction or mental health illness be saved or have a relationship with the King?  I like to think so.
“Praise the Lord, my soul, and forget not all his benefits-who forgives all your sins and heals all your diseases…” Psalm 103:2-3
Lastly, are we supposed to judge others?  Are we the ultimate judge?  Matthew 1:7 says that if we judge others, we will be judged with the same measure that we judged! OUCH!  I am the first one to admit being judgmental.  Some people judge addicts, I have judged/judge other moms.  It is truly pitiful.  Where in the world do we think that our “ways” are better than any others?  “God bases His judgment on truth."  We are commanded to “love our neighbors as ourselves!” James 2:8
“There is one lawgiver and judge who is able to save and to destroy. But who are you to judge your neighbor?” James 4:12
So did Whitney Houston go to heaven? 
Honestly, I don’t know. I would like to think so, but only God knows. 
When it comes to salvation, I can see both sides.
I would love to hear some other perspectives, so please, leave a comment!
What do you think?  Is salvation EASY?
