Why would people turn their back on the Good News? Do they think it's TOO good so it must not be true,...
Even we think it's too good to be true...
10 And ye are complete
in him, which is the head of all principality and power:
From G4134; to make replete, that is, (literally) to cram (a net), level up (a hollow), or (figuratively) to furnish (or imbue, diffuse, influence), satisfy, execute (an office), finish (a period or task), verify (or coincide with a prediction), etc.: - accomplish, X after, (be) complete, end, expire, fill (up), fulfil, (be, make) full (come), fully preach, perfec
This says we are already made perfect in Christ, in whom we died and are resurrected.
11 In whom also ye are circumcised with the circumcision made without hands, in putting off the body of the sins of the flesh by the circumcision of Christ:
12 Buried with him in baptism, wherein also ye are risen with him through the faith of the operation of God, who hath raised him from the dead.
13 And you, being dead in your sins and the uncircumcision of your flesh, hath he quickened together with him, having forgiven you all trespasses;
14 Blotting out the handwriting of ordinances that was against us, which was contrary to us, and took it out of the way, nailing it to his cross;
15 And having spoiled principalities and powers, he made a shew of them openly, triumphing over them in it.
Everything that came before is the shadow cast through the ages by this great and glorious body of Christ, which we are now. We in Christ are the ones that cast that shadow seen by the prophets of the Old Testament.
Hebrews 8:5 They serve at a sanctuary that is a copy and shadow of what is in heaven. This is why Moses was warned when he was about to build the tabernacle: "See to it that you make everything according to the pattern shown you on the mountain."
Hebrews 10:1 The law is only a shadow of the good things that are coming--not the realities themselves. For this reason it can never, by the same sacrifices repeated endlessly year after year, make perfect those who draw near to worship.
Which are a shadow of things to come; but the body is of Christ.
1 Corinthians 12:27 Now you are the body of Christ, and each one of you is a part of it.
