Why do we need the approval of others?
We all need approval, but how do we become addicted to this need? It often begins in our early years. If your parents withheld approval from you, if they were more focused on punishment and correction than affirmation and approval, this could be a major cause of your approval addiction. Likewise, if you never received recognition from other authority figures in your life, such as teachers and bosses, that could also fuel your intense desire and addiction to approval. It's always helpful to understand the source of our struggles, but using them as excuses does nothing but keep us powerless, in bondage to them. We're adults now; it's time to get over it and live free from needing other people to validate us.
How do we get over our need for the approval of others?
You don't! It's a basic need that's born in us. Some of us have a greater approval need than others, but we all need approval in order to survive, to thrive, tp be motivated and affirmed. Instead of asking other people to meet our need, and finding that it is never completely satisfactory or never quite enough, we need to live our lives for the approval of our Savior, Jesus Christ.
This requires us to have a clear assurance of our personal relationship with the living God. And that begins when we become His child through faith in Jesus Christ. Once that is firmly established, then we become more and more confident of God's approval, and of our assurance in how He sees us as we delve into the Word of God, learn it, love it, study it, teach it, read it, memorize it, and obey it. If you wanted a quick fix, sorry, I don't have one because there aren't any.
