I love Colossians 2:9-15, but like John 3:16, Colossians 2:12 says that faith is required:
Colossians 2:12
12Buried with him in baptism, wherein also y
e are risen with him through the faith of the operation of God, who hath raised him from the dead.
This whole circumcision of Christ is an operation performed by God, there's nothing you or I can do to facilitate that process except have faith in Christ. Colossians 2:9-15 goes into unnecessary, but interesting, details, John 3:16 just tells the person what they need to do and what their gift will be for obedience. If someone has sincere faith in Christ then God will keep His promises and each individual will get eternal life. Am I wrong?
“For from within, out of the heart of men, proceed evil thoughts, adulteries, fornications, murders, Thefts, covetousness, wickedness, deceit, lasciviousness, an evil eye, blasphemy, pride, foolishness: All these evil things come from within, and defile the man.”
Mark 7:21-23 KJV
his word and us believing is how the circumcision works it changes what’s in our heart he can take those type of hearts and this enters in through belief in Jesus and his word
“For
the word of God is quick, and powerful, and sharper than any twoedged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow,
and is a discerner of the thoughts and intents of the heart.”
Hebrews 4:12 KJV
The circumcision is this and all we can do
“And he said unto them, Go ye into all the world, and
preach the gospel ( his instrument of circumcision )
to every creature. He that believeth and is baptized shall be saved; but he that believeth not shall be damned.”
Mark 16:15-16 KJV
It works in us through faith to change a sinners hesrt to a righteous one because what’s in our heart of faith is going to bear fruit whether good or evil God is able to change us at the core through the hearing of faith
“So then
faith cometh by hearing, and hearing by
the word of God.”
Romans 10:17 KJV
as we grow in faith we learn that there are many things to do but we operate by faith as we grow and are changed those works begin to come out of us , just like the works of the flesh used to because of our hearts condition
Jesus is a heart surgeon , his word his scalpel and man always operates by the understanding and belief in the heart as he changes our Will it changes our actions by faith
“Wherefore, my beloved, as ye have always obeyed, not as in my presence only, but now much more in my absence, work out your own salvation with fear and trembling. For
it is God which worketh in you both to will and to do of his good pleasure.”
Philippians 2:12-13 KJV
your right it’s belief but to believe we have to hear what he said and let it become what we believe
