The first and best move you can make to build up your faith is to get your eyes off your problem and off yourself and onto Jesus. He is the Source of all your supply. He is utterly reliable and possesses all knowledge and all authority. Speak aloud the words of Hebrews 13:6, until they sink deep within your spirit: The LORD is my helper; I will not fear.
What can man do to me?
People may criticize, reject, ridicule, and persecute, but they can not take away your salvation, your relationship with Jesus Christ, your eternal home in heaven, or the joy, contentment, and inner strength the Lord imparts to you. With Christ, you have everything that truly matters in life.
Second, ask the Lord to give you the help you need. It is one thing to say,
The Lord is my helper, and another to say, “Lord, help me today,” or “Lord, help me right now in this situation.” You may need an answer to a problem, friendship, a good mentor or teacher, wise counsel, or extra energy and strength. Be specific in your requests to the Lord.
Third, encourage yourself by memorizing the Word of God and quoting it as often as you need a fear-buster of inner strength. Take Isaiah 41:10–13 to heart: Fear not, for I am with you; Be not dismayed, for I am your God, I will strengthen you, Yes, I will help you. I will uphold you with My righteous right hand.
Behold, all those who were incensed against you Shall be ashamed and disgraced;
They shall be as nothing, And those who strive with you shall perish.
You shall seek them and not find them; Those who contended with you.
Those who war against you Shall be as nothing, As a nonexistent thing.
For I, the LORD your God, will hold your right hand,
Saying to you, “Fear not, I will help you.”
Four promises are embedded in this passage:
1. The Lord promises to give us His presence.
2. The Lord promises to give us His power, which is vastly superior to our strength.
3. The Lord promises to give us His provision, which is more than sufficient.
4. The Lord promises to give us His protection against all of our enemies. Presence, power, provision, and protection, what more could you possibly need? Remind the Lord often of His fourfold promise to you.
And, finally, ask others to pray for you. Ask them to uphold you daily in prayer, and in turn, pray for them and for their success. We read in James 5:16, “Pray for one another, that you may be healed.”
What might the man in the example have done as he took his new job?
First, he might have said in the face of his tremendous challenge, “I don’t know all there is to know yet about this job, but the Lord knows. He will teach me, and He will help me get the information I need. He will give me discernment, wisdom, understanding, and energy to study this field and tackle this problem until I do know the information I need to know and I do have the answers I need to have.”
Rather than see the job ahead as overwhelming and monumental, he might have seen it as a great mountain to be climbed, step by step, bit by bit. He might have said to himself at the end of each day, “The Lord helped me through another day. I learned some new things. I did good work. I took a step in the right direction.”
At times of failure or error, he might have confessed errors to the Lord, asking, “Lord, help me to learn from this. Help me not to make this mistake again. Help me to remedy this error as quickly and completely as possible so that my mistake will cause no injury to the company or to any other person.”
The fact is, we all fail. If you haven’t failed yet at anything, trust me, you will! Every successful person has failed countless times. We all have failed to keep our word to God, to live up to what we know is right in God’s eyes, and to do our best in every situation and at every task. We all have failed to be as understanding, kind, and generous as we would like to be. If we focus on our failures, we can become buried by them. The good news is that God forgives our sins and He imparts to us His Holy Spirit to help us make changes in our lives, to grow, mature, and develop so that we overcome our failures and make fewer mistakes.
Every person alive has suffered loss. We may lose something precious.
But the good news is that if we obey God and continue to move forward in pursuit of the goals He has helped us to set for our lives, He is going to find a way to work all of our losses into a pattern that is positive and of eternal benefit to us. He will make us strong in areas where we have been weak. He will give us victories and rewards in areas where we have suffered loss in the past. He will turn all things to good.
It is also a fact that you will never please everybody. There will always be somebody who will criticize what you do, even if you have the most impeccable character and integrity of any man or woman on the face of the earth. Seek to please the Lord. Seek to fulfill what He has called you to do.
And let the criticism of others flow by you. Don’t internalize their negative comments. Don’t take them to heart or allow them to dictate what you do.
This is not to say that you should reject all godly counsel. Rather, you should reject all criticism aimed at destroying you, diminishing you, or discouraging you. The Lord never comes to steal, kill, or destroy you. That is the work of the enemy. (John 10:10.)
Don’t be surprised when fear emerges. Nothing good in life comes without a struggle against fear. The key is to run headlong at fear with your faith in Christ Jesus and your confidence firmly set in Him. You can overcome fear, and it is up to you to break through this success roadblock each and every time it rears its ugly head.
