“And being not weak in faith, he considered not his own body now dead, when he was about an hundred years old, neither yet the deadness of Sara’s womb:”
Diagnosing a weak faith is easy to do, and you do it by analyzing what a strong faith looks like. The verse above says that Abraham was “not weak in faith”; therefore, the way to figure out the symptoms of a weak faith is to analyze why Abraham’s faith was so strong. When I look at his faith, I discover four symptoms of a weak faith.
First, a believer with a weak faith looks at their weaknesses. The difference between Abraham and the person who has a weak faith is that Abraham knew that he was incapable, but He also understood that His God was capable. What God can do with your faith will be determined by whether you choose to dwell on your weaknesses or to focus on God’s omnipotence. You have a weak faith if you determine what you can do for God based on your abilities.
Second, a believer with a weak faith doesn’t believe in God’s promises. According to verse 20, Abraham “staggered not at the promise of God.” Your faith will never grow until you start believing that God will perform what He promises He will do. My question for you is this, when is the last time God didn’t come through on His promise? The answer to this question is NEVER. A weak faith says that God will never do it; a strong faith says that God promised it, so it will happen.
Third, a believer with a weak faith lets unbelief rule their decisions. It comes down to who you let make decisions for you. Your faith will continue to stay weak if you let unbelief dictate what you do for God. Unbelief has a strong argument that the impossible can’t happen, but unbelief focuses on man’s abilities and not on God’s power and promises.
Fourth, a believer with a weak faith is more concerned with self-image instead of living to give glory to God. Abraham lived by faith because He knew that faith would bring glory to God. My friend, one reason you are afraid to step out by faith is because you are concerned with what people will think about you if you fail. Let me ask you, what will people think about you when you succeed because God comes through on His promises and honors your action of faith? You can’t have a strong faith when you’re concerned about your self-image and what others will think about you if you fail.
Now, because something is weak doesn’t mean that it has to stay weak. If your body is weak, you work it out to strengthen your weak muscles. If you want to strengthen your faith, you must work it out. You don’t have to have a weak faith. You can have a strong faith if you will work it out. How do you start to strengthen your faith?
First, start from where you are with the faith that you have. Stop comparing your faith to someone with a stronger faith; just step out with the faith that you do have. You cannot make your faith stronger if you don’t act on it. Those with a strong faith were where you are right now, but they chose to use the faith they had and it became stronger. Your faith will become stronger if you act on whatever amount of faith you have.
Second, do a little more than you believe you can do. Doing a little more than you believe you can do is the key to strengthening a weak faith. Don’t do what makes you feel comfortable, but go out a little further and become uncomfortable and the faith you have will be strengthened.
