Hebrews 4:16

Let us therefore come boldly to the throne of grace, that we may obtain mercy and find grace to help in time of need.  

As a born-again believer, we have a covenant relationship with God.  That means we can come boldly before God making requests in our time of need.  We don’t have to beg but pray according to His word.  God said in His word that we are healed, and all our needs are provided for, and we need to reference the promises as we pray.  Be Bold and ask according to His word.
