Romans 16:25-27 English Standard Version
Doxology
25 Now to him who is able to strengthen you according to my gospel and the preaching of Jesus Christ, according to the revelation of the mystery that was kept secret for long ages 26 but has now been disclosed and through the prophetic writings has been made known to all nations, according to the command of the eternal God, to bring about the obedience of faith— 27 to the only wise God be glory forevermore through Jesus Christ! Amen.
I think Paul makes it clear here that obedience of faith is to glorify God.
We are human, we have not been perfected yet and as such we are subject to our own personal insecurities and emotional trauma.
Psalm 23:4 Even though I walk through the valley of the shadow of death, I will fear no evil, for you are with me; your rod and your staff, they comfort me.
Once we understand the purpose of the rod and the staff we may come to terms with how we can be comforted in times of trouble, being human. That is a matter of experiencing God more than it is a matter of just believing.
Isaiah 61:1-2 English Standard Version
The Year of the Lord’s Favor
1 The Spirit of the Lord God is upon me, because the Lord has anointed me
to bring good news to the poor; he has sent me to bind up the brokenhearted,
to proclaim liberty to the captives, and the opening of the prison to those who are bound;
2 to proclaim the year of the Lord’s favor, and the day of vengeance of our God; to comfort all who mourn;
With those words Jesus began His earthly ministry. By our obedience of faith that ministry continues today glorifying God.
