Is God’s grace partial to those with difficult life experiences?

Romans 3:23-24
23 for all have sinned and fall short of the glory of God, 24 and are justified by his grace as a gift, through the redemption that is in Christ Jesus,

2 Peter 3:9
The Lord is not slow to fulfill his promise as some count slowness, but is patient toward you, not wishing that any should perish, but that all should reach repentance.

To whom should we turn in all circumstances of life?

1 Corinthians 15:10
By the grace of God I am what I am

Psalm 51:1-2
1 Have mercy on me, O God, according to your steadfast love; according to your abundant mercy blot out my transgressions. 2 Wash me thoroughly from my iniquity, and cleanse me from my sin!
