Cure yourself of the condition of bothering about how you look to other people. Be concerned only with the idea God has of you.
Insecurity
Lysa Terkeurst
Mark Batterson
Pride is a by-product of insecurity. And the more insecure a person is, the more monuments they need to build. There is a fine line between ‘Thy kingdom come’ and ‘my kingdom come.’ If you cross the line, your relationship with God is self-serving. You aren’t serving God. You are using God. You aren’t building altars to God. You are building monuments to yourself.

The more insecure leaders are, the more they will invoke heavenly backing for their demands that their followers ‘tow the company line.’
Arthur W. Pink
If we expect people to pet and pamper us, disappointment will make us fretful. If we desire our pride to be ministered to, we are dejected when it is not. The secret of happiness is forgetting self and seeking to minister to the happiness of others. “It is more blessed to give than to receive,” so it is a happier thing to minister to others than to be ministered to.
John Ortberg

When we live in the love of God, we begin to pay attention to people the way God pays attention to us.
Jeremy Riddle
We’re no longer supposed to live in a conflicted state, unsure of ourselves, unsure about the God we serve, locked up in insecurity. We have a new nature, and at the core of this new nature is a thing called faith.
Priscilla Shirer
Let Paul’s identity sketch from Ephesians 1 embed itself into the floorboard of your deepest insecurities. You are: equipped through Christ with “every spiritual blessing” (v. 3) chosen in Him “before the foundation of the world” (v. 4) regarded as “holy and blameless before Him” (v. 4) adopted through the “kind intention of His will” (v. 5) redeemed and forgiven, “lavished” with grace (vv. 7–8) recipients of a glorious “inheritance” in heaven (v. 11) secured forever by “the Holy Spirit of promise” (vv. 13–14)
Dietrich Bonhoeffer
Earthly goods are given to be used, not to be collected. In the wilderness God gave Israel the manna every day, and they had no need to worry about food and drink. Indeed, if they kept any of the manna over until the next day, it went bad. In the same way, the disciple must receive his portion from God every day. If he stores it up as a permanent possession, he spoils not only the gift, but himself as well, for he sets his heart on accumulated wealth, and makes it a barrier between himself and God. Where our treasure is, there is our trust, our security, our consolation and our God. Hoarding is idolatry.
John R.W. Stott
Insistence on security is incompatible with the way of the cross. What daring adventures the incarnation and the atonement were! What a breach of convention and decorum that Almighty God should renounce his privileges in order to take human flesh and bear human sin! Jesus had no security except in his Father. So to follow Jesus is always to accept at least a measure of uncertainty, danger and rejection for his sake.
