Hebrews 4:16 KJV: Let us, therefore, come boldly unto the throne of grace, that we may obtain mercy, and find grace to help in time of need.
As a believer, you need to come to terms with the fact that you have unreserved access to the throne of grace where mercy and grace abound. Jesus made that possible when he paid for your sins on the cross. You no longer need to beg for mercy, simply come boldly and obtain it.
No man can survive without the mercy of God. We all need the mercy of God every day of our lives. Whenever you fail in your relationship with him, invoke his mercy upon your life and give him thanks.
Declare to yourself loud: Oh Lord, I invoke your mercy on my life, may your mercy speak for me in areas I have failed in my duties.
Heavenly Father, thank you for your mercy. I am grateful. Amen.
