"I will therefore put you in remembrance, though ye once knew this, how that the Lord, having saved the people out of the land of Egypt, afterward destroyed them that believed not." (Jude 5 KJV)
"So you see, faith by itself isn't enough. Unless it produces good deeds, it is dead and useless." (James 2:17 NLT)
Let me tell you something, all of those things Jesus spoke about regarding those bad seeds, as I was typing out the words, I was remembering times when I had bits and pieces of those experiences. Not that I stayed in those conditions, but that there were days when I didn't believe that I was saved; days when I had fallen away, feeling as if I didn't belong; days when work and pleasures were more important than serving the Lord.
Having been through the fire, if you will, I am somewhat more confident and secure about my belief in the salvation I have been given. There still are times when I feel discouraged and unworthy; but it is in those times that pick myself up and stand up like a man. And then there are times when I fall down to my knees and beg for forgiveness! If you don't know what all that means, then you probably haven't studied the Book of Job.
Here is the thing that believing actually means when it comes to following Christ: Just as Jesus said to His disciples, ""The most important commandment is this: 'Listen, O Israel! The LORD our God is the one and only LORD. And you must love the LORD your God with all your heart, all your soul, all your mind, and all your strength.' The second is equally important: 'Love your neighbor as yourself.' No other commandment is greater than these."" (Mark 12:29-31 NLT)
Basically, if you love God as you should, then you will do what He tells you to do, and you believe what He says, and you put forth the effort to listen and obey, even if you don't really want to! It sounds really simple, but it sometimes is really hard! When those times come when we are not willing or have excuses for ways out, remember that Jesus wept and begged the Father, saying, "My Father! If it is possible, let this cup of suffering be taken away from me. Yet I want your will to be done, not mine."" (Matthew 26:39 NLT)
When I think of it that way, my choices get less important...
""Is anyone thirsty? Come and drink - even if you have no money! Come, take your choice of wine or milk - it's all free! Why spend your money on food that does not give you strength? Why pay for food that does you no good? Listen to me, and you will eat what is good. You will enjoy the finest food. Come to me with your ears wide open. Listen, and you will find life. I will make an everlasting covenant with you. I will give you all the unfailing love I promised to David."" (Isaiah 55:1-3 NLT)
