There are many Scriptures that answer this question. One of the best sections of the Bible that give a list of the blessings a Christian receives "in Christ" is (Ephesians 1:1-14).
Listed here are a few of the blessings "In Christ" and their corresponding verses.
"In Christ", one gets "All Spiritual Blessings”
"Blessed be the God and Father of our Lord Jesus Christ, who has blessed us with every spiritual blessing in the heavenly places in Christ" (Ephesians 1:3).
“In Christ”, one finds “Grace”
“to the praise of the glory of His grace, which He freely bestowed on us in the Beloved” (Eph. 1:6)“
In Christ”, one receives “Redemption” and “Forgiveness”.
“In Him we have redemption through His blood, the forgiveness or our trespasses, according to the riches of His grace” (Ephesians 1:7).
“In Christ” we Receive the “Holy Spirit”.
“In Him, you also, after listening to the message of truth, the gospel of your salvation—having also believed, you were sealed in Him with the Holy Spirit of promise, who is given as a pledge of our inheritance, with a view to the redemption of God’s own possession, to the praise of His glory”. (Eph. 1:13-14).
These are just a few of the blessings that a Christian receives. If you are not "in Christ", feel free to contact us if you want to learn more. We desire to see all "In Christ" and ultimately "in heaven".
"For you are all sons of God through faith in Christ Jesus. For all of you who were baptized into Christ have clothed yourselves with Christ. There is neither Jew nor Greek, there is neither slave nor free man, there is neither male nor female; for you are all one in Christ Jesus" (Galatians 3:26-28)
