God is love and His main characteristics are loving-kindness, righteousness and justice. Jesus Christ as a the Son of God exemplified these attributes of love when He was here on earth.
Therefore, the children of God, the true followers of Christ must establish themselves in those characters. They must practice spiritual love, physical love, cooperative love, understanding love and enjoy it. They must not depend on their emotion and feelings to love. Our love must depend on the WILL of love. Christ’s love was always manifested, unhindered, uninterrupted because of His WILL to obey God, not because of emotions. A truly born-again Christian must love everybody despite all odds, even as Christ loves the whole world and gave his life for the redemption of mankind.
The beauty of Christian life is based on having peace with all man and love for mankind.
1. Christ loves the undeserving and the unlovable (Roman 5:6-10; Matthew 26:66-75; 28:9-10).
2. Christ loves willfully (John 10:15-18);
3. He loves at all time (John 13:1)
4. He loves absolutely (John 13:15)
5. He loves sacrificially (John 15:13; Philippians 2:5-
6. He loves purposefully (Ephesians 5:25)

God expects His children(real born-again Christians) to love everybody, not because of what he or she can get from the person but because it is Christ’s ordained order for us to love sacrificially.
You do not love anybody enough until your love is a sacrifice like Christ’s!
Obedience to God’s words concerning love brings happiness and peace of the mind. Happiness and peace from above has a wonderful guarantee. Happiness and peace from above will never fail. Holy peace equals to love. Cheerfulness and love conquers in ugly situations. The secret of wining and progress is through peace and non- violence. The man who uses violence is being regarded as cruel and inhuman; and must be hated by people aroundhim and at last he must fail. Whereas, the man who uses peace and non-violence is a man of goodwill and is being loved and respected by people around him; he must win in all life endeaviours. The is because he preaches the message of love and brotherhood; peace of the mind; peace amongst family, community and society at large. He tries to bring happiness and peace by showing compassionate love towards the poor ones around him at all times.

Patience, tolerance, endurance and perseverance uplifts love. Forgiveness is what keeps peace.
Christians must be greatly influenced by the teachings of Jesus Christ. Christ had said that if anyone slapped you on one cheek, instead of retaliating, you should turn your other cheek also (Matthew 5:39), Friend, you need grace to overcome this. Christ was preaching forgiveness, instead of revenge, and that is what Christians must uphold too.
He practicalised it by the Willful suffering, death on the Calvary tree in order to reconcile fallen man with the Almighty God.
Christians must believe in fair play and justice. Christians must love many with all their heart, soul and body in all things. By making people around us mentally and physically comfortable and helping them to learn to respect each other’s right and privilege. You can maintain peace.
