That is a scriptural truth.
1 Peter 2:5 Ye also, as lively stones, are built up a spiritual house, an holy priesthood, to offer up spiritual sacrifices, acceptable to God by Jesus Christ.
In the Old Testament it was the priest alone who could approach the throne of God. Jesus was the perfect sacrifice and that veil separating us from the Father was torn in two.
Matthew 27:51 And, behold, the veil of the temple was rent in twain from the top to the bottom; and the earth did quake, and the rocks rent;
We can now go boldly before the throne of God having been covered by the blood of Jesus.
Hebrews 4:16 Let us therefore come boldly unto the throne of grace, that we may obtain mercy, and find grace to help in time of need.
Excellent response.
