It is because you really are his sons that God has sent the Spirit of his Son into your hearts to cry “Father, dear Father”. You, my brother, are not a servant any longer; you are a son. And, if you are a son, then you are certainly an heir of God through Christ.

Galatians 4:6-7 (Phillips)

Our salvation is trinitarian.

All three members of the Trinity — the Father, the Son, and the Holy Spirit were and are fully involved in our salvation. Salvation is not something that we can earn or keep through our self-efforts, but rather it is something we receive humbly through the supernatural grace of Christ and His imputed righteousness. This is why we cry out to God “Abba Father”, as the Holy Ghost reveals to us the reality of our sonship in Christ.

The Apostle Paul encourages us to walk in the light of our new identity in Christ. Our new identity is that we are no longer slaves but sons and daughters of God. Justification elevates us to the status of sonship; sanctification grows us to the stature of sonship. We become who we already are in Christ. It is not by striving but by imitating Him through the power of His Spirit working in and through us.

The work of the Trinity was so perfect that nothing is lacking or missing when it comes to our salvation. God, who begins a good work in us, will also perfect us in the image and likeness of Christ. Our closeness to God is defined by our image of God and who we are and where we stand in God's eyes.

A slavish mindset creates fear and discouragement. You will always ask yourself, "Have I done enough?” or "Will God forgive me if I make the same mistake again?" or "Am I truly saved if I struggle with habitual sin?" Eventually you will become a slave to those thoughts and lose your joy of salvation. This makes our worship hard and service a drudgery.

Salvation isn’t about Jesus doing His part, and you doing yours! If that’s the case, then you’ll always have to meet certain standards of acceptability and belonging. Instead, keep reminding yourself of what Jesus has already done for us by hearing the gospel again and again.
