God desires to empower you through the Holy Spirit to live a Christ-directed life. As you continue to breathe spiritually (confess your sin and claim the fullness of the Spirit), you will experience a deepening fellowship with God enabling you to grow in Christian maturity.
1) What does it mean to grow in Christ?
It means to increase in your knowledge of Christ, your love for Him, and in obedience to Him.
“Now this is eternal life: that they may know You, the only true God, and Jesus Christ, Whom You have sent” (John 17:3).
