God the Father has dignified every person with the freedom of choice. The Father wants us to exercise our freedom by choosing the glorious sonship that He prepared for us in Christ Jesus.
The choice that we each must make is our sanctification as a son of God. This means choosing to remain connected to the fellowship of the Father, Son and Holy Spirit, by abiding in Their fellowship. Joh 15:4-8. To do this, we must first recognise that the freedom of choice does not begin with us. Jesus made this clear to His disciples, saying, ‘You did not choose Me, but I chose you and appointed you that you should go and bear fruit, and that your fruit should remain, that whatever you ask the Father in My name He may give you.’ Joh 15:16.
The promise that belongs to those who choose what God has chosen for them is the blessing of being born of the Spirit as a son of God! Gal 3:14.
