Drawing Near to God in Enduring Faith

10:19 Therefore, brothers and sisters, since we have confidence to enter the sanctuary by the blood of Jesus, 10:20 by the fresh and living way that he inaugurated for us through the curtain, that is, through his flesh, 10:21 and since we have a great priest over the house of God, 10:22 let us draw near with a sincere heart in the assurance that faith brings, because we have had our hearts sprinkled clean from an evil conscience and our bodies washed in pure water.

James 4:8

4:8 Draw near to God and he will draw near to you. Cleanse your hands, you sinners, and make your hearts pure, you double-minded.
