according to God, the Lawgiver, the two most important commands r these: first, love the Lord your God with all your heart, with all your soul, with all your mind, and with all your strength; second, love your neighbor as yourself (Mark 12:28-31).
notice, it is not a suggestion, but a command. love is hard work. it does not come naturally to us. if loving God and loving others came naturally to us, then, there is no need of a command. naturally, we r inclined to love only ourselves.
loving others and especially, loving God goes against our fallen nature; hence, this makes loving God and loving others rather an impossible task. this huge task requires the need of something more than natural - a supernatural support. in other words, we need God's help to put Him and others before ourselves. however, just as God's help is crucially necessary, so is the need for our willingness to love.
