For we are made partakers of Christ, if we hold the beginning of our confidence stedfast unto the end; Hebrews 3:14 KJV
This Bible verse has pi (π) as its number: 3.14.... Hebrews 3:14
A circle has its beginning and ending on the same point. And (π) is used to calculate the curved length of all circles (the circumference) if the distance to the center of the circle is known. And we are partakers of Christ if we begin and end with confidence in Jesus.
If the radius of the circle leads to the center, and if the cross is two radii, then what part of Jesus was at the center? His heart was at that point.
The center of the circle would be the heart of God.
The verse makes it clear that we are partakers of Christ if we continue with the confidence we have in Jesus until the end.
