2 Corinthians 1:20-22 gives us a picture of our position in Christ. Right now, not at some future date. It says, " For all the promises of God in Him (Jesus) are yes, and in Him amen, unto the glory of God by us."
Image that! The glory of God by us. He has distilled by His Spirit in us great authority and position. Not at some future date, but right now.
The passage continues, " He has also sealed us, and given the earnest (down payment, just a portion) of the Spirit in our hearts."
The only One who is worthy to open the 7 seals in the Book of the Revelation of Christ has already sealed each individual Believer. What an awesome thought.
In this context He admonished us to not labor or worry about meat that perishes, but for the meat (life style and beliefs) that endure unto everlasting life which the Son of Man shall give to you, for Him hath the Father sealed. ( John 6:27)
This is a major lifestyle change compared to our friends, family and coworkers. We are set aside for Him. We need to appropriate this and realize our position in heavenly (spiritual) matters.
It is our faith in these concepts, these truths, that overcomes the world. We are admonished to not grieve the Holy Spirit of God whereby we are already sealed (set apart, locked into) until the Day of Redemption. (Ephesians 4:30)
How can we grieve the Holy Spirit of God? In the same manner in which the Children of Israel did in the Wilderness Journey; they did not believe what God said. Do not fall into this catagory. We need to have a full revelation of our position in Christ. We must believe and appropriate the authority He has given us as Believers in every circumstance in our daily lives.
He who has the power to open the seals at the end of this Age is called Faithful and True. He cannot lie. He will never fail us or forsake us; we are His - bought with a very heavy price.
