It's not about doing new things.
It's not about new ideas, or finding novelty in our levels.
That level of newness is not enough.
Everything about us needs to be new.
"And he that sat upon the throne said, Behold, I make all things new. And he said unto me, Write: for these words are true and faithful." (Revelation 21: 5)
Jesus is in the business of making things new.
"But they that wait upon the LORD shall renew their strength; they shall mount up with wings as eagles; they shall run, and not be weary; and they shall walk, and not faint." (Isaiah 40: 31)
Jesus enacted the New Covenant for us:
"But now hath he obtained a more excellent ministry, by how much also he is the mediator of a better covenant, which was established upon better promises." (Hebrews 8: 6)
"And to Jesus the mediator of the new covenant, and to the blood of sprinkling, that speaketh better things than that of Abel." (Hebrews 12: 24)
Jesus invites us to renew our minds:
"And be not conformed to this world: but be ye transformed by the renewing of your mind, that ye may prove what is that good, and acceptable, and perfect, will of God." (Romans 12: 2)
To recognize our new selves in Christ:
23And be renewed in the spirit of your mind; 24And that ye put on the new man, which after God is created in righteousness and true holiness." (Ephesians 4: 23-24)
"Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new." (2 Corinthians 5: 17)
We are made new creatures in Christ Jesus, because Jesus is all about making us new and renewed!
