On God my salvation and my glory rest;
The rock of my strength, my refuge is in God.
He is our salvation, but He is also our glory. We have nothing to glory in. If there is anything good, it is because of God's work in us. Our glory rests in Christ.
Do you have something about yourself which you are proud of? Don't be. If there is anything in you or about you that is worthy of glory, it is because of Christ.
