Whose actions should we focus on in our spiritual life?

Focusing on my own actions in my spiritual life is very dangerous.

The reason is that if I look at my righteous deeds,

I may rely on my own self-righteousness instead of the righteousness of Jesus.

Similarly, if I look at my sinful actions,

I might struggle with guilt due to my own unrighteousness,

neglecting to rely on Jesus, who shed His blood on the cross for my sins.

Therefore, I must always focus on the actions of Jesus on the cross and live by faith

(While reading Romans 9:11).
