Love is all we need. It is easy to give, easy to receive but how can we give when we know we cannot receive it back because of some circumstances? The Holy Bible teaches us about unconditional love.
According to Matthew 5:43-48
"You have heard that it was said, 'Love your neighbor and hate your enemy. But I tell you, love your enemies and pray for those who persecute you, that you may be children of your Father in heaven. He causes his sun to rise on the evil and the good, and sends rain on the righteous and the unrighteous. If you love those who love you, what reward will you get? Are not even the tax collectors doing that? And if you greet only your own people, what are you doing more than others? Do not even pagans do that? Be perfect, therefore, as your heavenly Father is perfect."
Love is easy to give especially to persons that you truly care and love you too. However, it is hard to love those who are against you, who caused trouble for you, who always gives negative situation to you. God, in the Bible advise us to love those who needs love more than the people who always received loved from us. Love is given to all for free and fairly.
On the other hand, It really feels good to be loved but there are times that world round you forgets that. Even worse, sometimes that person can be your spouse. Whether that love is void or lacking, it does not mean that you cannot still love them. Marriage is about unconditional love. Don't make your love for them be dependent on theirs for you.
Unconditional love means it is beyond the measurement of humans. It means that it is unfathomable. Just as unconditional as God gives us His only son to die for all the sinners. Love is God and God is love.
