You gave us Galatians 4:6 to go with the choice that God is our Father >
"And because you are sons, God has sent forth the Spirit of His Son into your hearts, crying out, 'Abba, Father!'" (Galatians 4:6)
There are fathers who are very personal with their children. So, calling God our "Father" can mean He is very personal with each of us. And sending His own Spirit into our hearts is indeed very personal.
"Now hope does not disappoint, because the love of God has been poured out in our hearts by the Holy Spirit who was given to us." (Romans 5:5)
So, this is a basic of Christianity, how God in us shares His own love with us. We experience this. God's love is kind and personal and having Heaven's quality of pleasant rest > Jesus says >
"you will find rest for your souls." (in Matthew 11:28-30)
Our Father loves us by correcting us (Hebrews 12:4-14) so we live in His "rest for your souls" of His love. And we love one another, by helping each other to rest in Jesus. Because our Father wants us to love, like this. And we desire to please Him.
