Last night we spoke about 'the doctrine of impeccability'. Jesus was both God and man... fully human and fully divine... God by nature is not sinful so on one side of the coin of the incarnation Jesus would not sin. Satan did however tempt Christ and in full identification with us Jesus made choices and chose not to sin. He was and is impeccable. Both sides of the coin reveal the fullness of Christ's divine person.
The result of that impeccable life has been placed on the account of people who believe in Christ.
"And because of him you are in Christ Jesus, who became to us wisdom from God, righteousness and sanctification and redemption," - 1 Corinthians 1:30 ESV
We can say 'yes' or 'no' or we can walk in a powerful liberty that has been given as a free gift.
"As surely as God is faithful, our word to you has not been Yes and No. For the Son of God, Jesus Christ, whom we proclaimed among you, Silvanus and Timothy and I, was not Yes and No, but in him it is always Yes. For all the promises of God find their Yes in him. That is why it is through him that we utter our Amen to God for his glory. And it is God who establishes us with you in Christ, and has anointed us," - 2 Corinthians 1:18-21 ESV
Every promise God has made you and I is given through Christ and in Christ. The perfect life of God is found in Him.
All the 'should's of life have been accomplished in Christ. It is finished! Now we have the liberty to live in a 'Yes and amen' life in Christ.
