'Steadfastly' in the Bible

And He was saying to them all, “If anyone wishes to follow Me [as My disciple], he must deny himself [set aside selfish interests], and take up his cross daily [expressing a willingness to endure whatever may come] and follow Me [believing in Me, conforming to My example in living and, if need be, suffering or perhaps dying because of faith in Me].

Now when the time was approaching for Him to be taken up [to heaven], He was determined to go to Jerusalem [to fulfill His purpose].
