'Cleaving' in the Bible

Jesus called the crowd together with His disciples, and said to them, “If anyone wishes to follow Me [as My disciple], he must deny himself [set aside selfish interests], and take up his cross [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].

but these have been written so that you may believe [with a deep, abiding trust] that Jesus is the Christ (the Messiah, the Anointed), the Son of God; and that by believing [and trusting in and relying on Him] you may have life in His name.

The love unfeigned: abhorring the evil; cleaving to the good;
