Real love, genuine agape love is unconditional, period. If you doubt this truth, re-read Paul in his first letter to the church at Corinth. He boldly tells the church – a church battling crippling sins – that “love is kind” and “keeps no record of wrongs.”
And in his first letter, John writes:
And we have come to know and to believe the love that God has for us. God is love, and the one who remains in love remains in God, and God remains in him.
John doesn’t write, “The one who remains in God remains in love.” Rather, he turns it on its heels and states emphatically that “the one who remains in love remains in God.” You cannot hate people who you are able to see and touch while you claim to love God. You can not refuse to forgive others while expecting God to forgive you. Frankly love and hate are like oil and water – incompatible in the mix.
You can not be a Christian and hate people.
