My wife Joan’s favorite Bible verse is: “…you shall love the Lord your God with all your heart, with all your soul, with all your mind and with all your strength. This is the first commandment. And the second like it, is this: You shall love your neighbor as yourself. There is no other commandment greater than these (Mark 12:30-31, NKJV). This was Jesus speaking.
My favorite is: “…God demonstrates His own love toward us, in that while we were still sinners, Christ died for us (Romans 5:8, NKJV).
A close second is: “For by grace you have been saved through faith, and that not of yourselves, it is the gift of God, not of works, lest anyone should boast.” (Ephesians 2:8-9, NKJV).
