Forgiveness and Righteousness

"How has the pandemic altered your life? One of the things we've learned is how important our relationship with Jesus Christ is. So often we give it little more than lip service. I hope and pray that many are realizing their faith is genuine, rock-solid, and stronger than ever. * The Book of Romans is the case for grace. We read, "or all have sinned and fall short of the glory of God, and are justified by his grace as a gift, through the redemption that is in Christ Jesus..." Romans 3:23-24 * Please explain 1 John 5:6 "This is the one who came by water and blood, Jesus Christ; not with the water only, but with the water and with the blood." * If God decides who he wants to be saved and those whom He doesn't, doesn't that take freewill out of the picture? What are your thoughts? Thanks
