Above all, have fervent and unfailing love for one another, because love covers a multitude of sins [it overlooks unkindness and unselfishly seeks the best for others]. 1 PETER 4:8 AMP
God, Who is Love, unconditionally extended His love toward us and offered us His eternal communion.
For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.
John 3:16 KJV
God loves you so you should love Him and others (especially other believers).
Jesus said unto him, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind. This is the first and great commandment. And the second is like unto it, Thou shalt love thy neighbour as thyself. On these two commandments hang all the law and the prophets. Matthew 22:37-40 KJV
He gave us His love so that we could love like He does.
And hope maketh not ashamed; because the love of God is shed abroad in our hearts by the Holy Ghost which is given unto us. Romans 5:5 KJV
