In The Name of Allah, The Most Merciful, The Bestower of Mercy.

When Allah enables a person to be steadfast upon the true religion, the true methodology ordained by Allah, and the sound creed, this is a blessing from Allah, thus a person should not be deceived by himself, become boastful, or arrogant; rather, he should humble himself before Allah – the Lord of all worlds- and thank Him for this; humble himself to Allah, that Allah – Glorified be He – safeguards his (adherence) to his religion, keep him away from pitfalls and deviation, and not to slacken.

فَلَا يَأْمَنُ مَكْرَ اللَّهِ إِلَّا الْقَوْمُ الْخَسِرُون

None feels secure from the Plan of Allah except the people who are the losers. [Al-A’raf 99]

Therefore, we should beseech Him all the time that He makes our hearts steadfast.
