Its the closest relationship
Galatians 4:6 And because you are sons, God has sent forth the Spirit of His Son into your hearts, crying out, “Abba, Father!”
How are we sons & daughters? By faith in Christ. Not earned but then He also gives us His Spirit within us as a guarantee. Our hearts are only now able to be in communion & fellowship with God. We know Him as a Father, a Dad. My kids are free to approach me whenever, however, and for whatever any day of the week. They dont question if we can talk. They dont arrange discussions thru a third party. We just meet up. We go straight to the topic. No formalities, is what Im saying. This is the glorious relationship we have our LORD. We approach Him anytime and for anything. We know Him as a Good Father but only as we have His Spirit. Some dont experience God as their Father due to never being born again. Thank You Father that You opened this up to us.
