We are sinners there is no requirement for God to be gracious to sinners yet because we know he sent and gave his best, his Son, to die and pay for our sins God can be gracious and is faithful to sinners who believe in the Lord.
Our prayers in many cases are mixed with our tears, yet, we must look at Jesus, the Gift of God on the cross and we can be convinced - God can be gracious to us.
Watch this promise below. It is so magnanimous our mind find it hard to wrap around it; but it is there, we did not write it, the HS did. It is for us, sinners begging for mercy from an Almighty God. Look at the things you have been provided, food on the table, roof above your head, alive today reading this post. Things could be worst, but if this is not what you are experiencing, turn to God and ask him to be gracious to you on account of Christ. He will and has, you will see all things will work together for your good.
