When it comes to loving God, the risk is all His.
True love is about self sacrifice. Giving all that you have to love someone else and not doing it to receive that love in return.
You risk it all when you pour your love into someone else, you make yourself vulnerable to being hurt. You never know for sure if the other person truly loves you back. You cannot read their hearts.
But you can place your trust in God’s heart, because there has been no greater love shown than when He gave His only begotten Son to be sacrificed for us, so that we may be forgiven, and know mercy.
So when Jesus asks us to deny ourselves, and take up our cross, and follow Him, that’s what it means to love Him.
It does make us vulnerable, by exposing our hearts and true motives, but because He already loved us first, the risk is all His.
