It can be two things:
1. You gave it all to a person who means the world to you until you have nothing more.
2. You lost hope and you don’t trust the system of love anymore,
Both happened. Both no good.
Many things can drain love from your system. And when you are completely empty, bitterness clouds you from getting the best out of life. You have to have a solid love-source so that you will never run out of it and hence you can share it to others.
Most of the time this world is all about making a ‘good-investment’. While in earthly matters you have to consider a lot of things to make sure you’ll get the benefit, loving God is proven and guaranteed to let you gain a lot of benefits. If you let Him, He will make you a person who is never running out of love. Bitterness would be a non-existing word for you.
The truth is I have never seen a single person who is full of love and bitter at the same time. It’s a solid case, you have to get rid of bitterness so that you can be full of love, or (by your choice) the other way around.
To be steadily full of love, come to the right source, God.
I can do all this through him who gives me strength. (Phil 4:13)
His Grace is sufficient and we all know that it is true. So here’s what we are going to do: first time in the morning, come to the unlimited love-source, God, read that bible, pray.
Be someone who has so much love to give.
Be the light that brighten up the surrounding.
Be right that the wrong will be shameful.
Be so kind-hearted that crushes bad intention.
Be Christ-like that everyone can see His love inside of you.
I pray that from his glorious, unlimited resources he will empower you with inner strength through his Spirit. (Eph 3:16)
