Nope. The New Covenant is not yet in effect. Stick with the Gospel of Grace given to Paul for all of us today in this dispensation of grace.
BTW
It’s true that the New Covenant is not yet in its
full application, because the promises of perfect peace, universal knowledge of God, and the restoration of all things (Jeremiah 31:31–34) will be completed when Jesus returns and God’s kingdom is fully established. However, Jesus did begin the New Covenant during His ministry and sealed it with His own blood at the cross.
At the Last Supper, Jesus said:
“This is My blood of the new covenant, which is shed for many for the remission of sins”(Matthew 26:28; Luke 22:20). From that moment, He consecrated the covenant with His own life. When He died,
“the veil of the temple was torn in two from top to bottom” (Matthew 27:51), showing that through Him, those who believe now have direct access to God.
This access is for those who truly believe in Him, follow Him, and do His Father’s will. Jesus Himself said:
“Not everyone who says to Me, ‘Lord, Lord,’ shall enter the kingdom of heaven, but he who does the will of My Father in heaven” (Matthew 7:21).
Even before His death, Jesus taught about this new relationship between God and His people. In John 14:6 He said,
“I am the way, the truth, and the life. No one comes to the Father except through Me.” And in John 10:9,
“I am the door. If anyone enters by Me, he will be saved.” These words show that He is the only access to God—a truth symbolized when the temple veil was torn.
Jesus also described the growth of this covenant and His kingdom in the
parable of the mustard seed:
“The kingdom of heaven is like a mustard seed, which a man took and sowed in his field, which indeed is the least of all the seeds; but when it is grown it is greater than the herbs and becomes a tree, so that the birds of the air come and nest in its branches”(Matthew 13:31–32). In this picture, the mustard seed represents the kingdom starting small—through Jesus’ ministry and sacrifice—and then growing until it reaches its full size in the future. The seed was planted at the cross, and the full-grown tree will be seen when He returns.
The prophets foresaw this covenant long before Jesus came. Jeremiah 31:31–33 speaks of a new covenant where God’s law will be written on hearts, and Ezekiel 36:26–27 promises a new spirit to help God’s people walk in His ways. Jesus began fulfilling these promises when He sent the Holy Spirit at Pentecost (John 14:26; Acts 2:1–4), but the complete transformation of the world will come at His return.
So, while the New Covenant is not yet in its
final and complete form, it is already in motion. Jesus started it, sealed it with His blood, and opened the way for all who believe, obey, and remain in Him to have fellowship with the Father now. The complete fulfillment will be when He comes again, just as the mustard seed grows into the great tree—it begins small but ends in fullness.
