There is a big difference between believing in God and believing God.
Lots of people believe in God. According to a study by Cambridge University poll in 2005, 88% of the world's population said that they believed in God. James 2:19 says "You believe that God is one; you do well. Even the demons believe—and shudder!" Even the demons believe in God. Simply put, you're not unique if you believe in God.
Contrary to popular belief, believing in God is easy. Everyone believes in something. It's natural for people to believe in something bigger than themselves. Now some people may call it God, some people may call it a higher power, some people may even call it The Force. But almost everyone believes in something bigger. That's no surprise considering Ecclesiastes 3:11 says that "He has put eternity into man's heart."
On the flip side, far fewer people actually believe God.
What do I mean by believing God?
I mean believing God's promises. Believing that God is who He says He is and believe He will do what He said He will do.
- God has promised to supply every need we have. (Phillippians 4:19)
- God has promised that His grace is sufficient for us. (2 Corinthians 12:9)
- God has promised that His children will not be overtaken with temptation. (1 Corinthians 10:13)
- God has promised us victory over death. (1 Corinthians 15:57)
- God has promised that all things work together for good to those who love Him. (Romans 8:28)
- God has promised that those who believe in Jesus will be saved. (John 3:16)
- God has promised His people eternal life. (John 10:27-28)
I think the true litmus test for a Christian is not whether they believe in God, but if they believe God.
God has promised us so much. He will take care of every need. His grace is sufficient through every trial. We will not be overtaken by temptation that we cannot handle. We have victory over death. No matter the situation, it will always work together for our good. Through Jesus we are saved from our sins and guilt and shame and have eternal life in Him.
Do you believe these promises? Do you live like these promises are true for you?
Or is your life still filled with worry, anxiety, control, fear, guilt, shame, and sin?
If the answer to the latter is yes, let it all go. The promise under all of the other promises is ultimately freedom. Freedom from everything holding you back living the abundant life God promised you when you were saved. I don't mean abundant financially, I mean spiritual abundance. A life that is rid of everything that is not the fruit of the Spirit.
God's promises are true for you today and for the rest of your life. Embrace them. Believe them.
Don't focus so much on your belief in God that you never take the time to actually believe God.
