Certainly there are many Christians who know very little about true fellowship with God, although they are children of God. This relationship has been established because of Faith in the finished work of the LORD Jesus Christ. They have salvation, BUT experience very little of the true joy of salvation.
What the member of the Body of Christ must come to know, is that we have been blessed “with all spiritual blessings in the heavenlies in Christ.” Ephesians 1:3 . “He that spared not His own Son, but delivered Him up for us all, how shall He not with Him also freely give us all things?” Romans 8:32 . “All are yours: And we are Christ’s and Christ is God’s.” 1 Corinthians 3:23.
Through the Faith in the LORD Jesus Christ we have BEEN:
“Delivered from the wrath to come” 1 Thessalonians 1:10
“Delivered from the power of darkness” Colossians 1:13
“Delivered from the fear of death” Hebrews 2:15
“Delivered from the law” Romans 7:6
“Delivered from this present evil age” Galatians 1:4
Through the Faith in this same LORD Jesus Christ we have BECOME:
“Partakers of the Divine nature” 2 Peter 1:4
“Partakers of His holiness” Hebrews 12:10
“Partakers of His sufferings” 1 Peter 4:13
“Partakers of the heavenly calling” Hebrews 3:1
This is because we are partakers of Christ. Hebrews 3:14 . Christ is our righteousness, our holiness, and our redemption. 1 Corinthians 1:30.
The Christian’s spiritual resources are unlimited, but very few Christians ever learn how to possess their possessions.
Beginning as a newborn babe in Christ, the believer is exhorted to add to his faith, virtue; and to virtue, knowledge; and to knowledge, self-control, patience; and to patience, godliness; and to godliness, brotherly kindness; and to brotherly kindness, love; and thus to grow in Grace and in the knowledge of the LORD Jesus Christ. 2 Peter 1:5-7 ; 2 Peter 3:18.
