Do you always doubt yourself?
Do you secretly compare yourself to your friends and family?
Do you avoid taking proactive actions because you feel insecure?
We all have our own kinds of insecurities.

In nothing be anxious, but in everything, by prayer and petition with thanksgiving, let your requests be made known to God. Philippians 4:6
But what does being insecure mean?
Being insecure means lacking confidence in yourself or the situation in which you are in. It means not trusting ourselves fully at that moment. Being insecure means feeling fearful or anxious about yourself or something.
How do we overcome insecurity and live confidently?
Find Out What Triggers Your Insecurity
You need to find out what triggers your insecure thoughts in order to know the right way to deal with them. Let’s say you always think that you’ll amount to nothing.
You need to find out why you think that way. It could be that you were told you would never amount to anything when you were young. Or your parents always compared you to your siblings.
Knowing why you think that way will help you to deal with the lies that you were fed when you were young.
While not all insecure thoughts are triggered by the devil, we need to be aware of his schemes so that we don’t fall into his traps.
The enemy will remind you of some bad experiences that you went through so that you can keep living in a cycle of defeat.
While you cannot change what happened, you should not let it define you.
Shift Your Focus
The reason why we struggle with insecure thoughts is that we focus on self. But the truth is, we shall never be good enough in and of ourselves.
We are imperfect human beings, and that means that we shall always fall short in certain areas of our lives.
To overcome insecurity, we need to shift our focus from self to Jesus. When feelings of doubt come, remember that you can do all things through Christ who strengthens you.

I can do all things through Christ, who strengthens me. Philippians 4:13
When the devil reminds you about your failures, remind yourself that Jesus has made you victorious through the cross.
Do not let the devil put you down because you are a new creation. He can no longer define you by your past because Jesus has set you free from all your past failures.
Rest In Jesus
Fighting insecurity in your own strength will only cause you to lose the battle. When thoughts and feelings of insecurity come into your mind. You need to rest in Jesus because he is your confidence.
The devil wants you to always be insecure, so he’ll fight you with all kinds of thoughts. You need to put your confidence in Christ and rest in his finished work.
Like the Psalmist in Psalm 27:5, see yourself hidden in the shelter of God.

For in the day of trouble, he will keep me secretly in his pavilion. In the secret place of his tabernacle, he will hide me. He will lift me up on a rock. Psalm 27:5
Rest knowing that God has set you high upon a rock.
All in all:
We all struggle with insecurity from time to time. But we need to remember that anxious thoughts are not true.
It is only the word of God that is true. Our identity is found in Christ and not in self.
Find out what triggers your insecurity, shift your focus from self to God, and rest in Jesus.
