When you know you were created by a perfect all-loving God that desires eternal fellowship with you, it is hard not to fall in love with him completely. 

God did make eternal fellowship with him a choice though. 

We have to seek it and ask for it. 

Matthew 7:7-8:
Ask, and it will be given to you; seek, and you will find; knock, and it will be opened to you. For everyone who asks receives, and he who seeks finds, and to him who knocks it will be opened. 

God will take your love and love you back anytime, in any part, of your life. 

But let me encourage you to do it right out of the gates. 

This all reminds me of the story of Saint Augustine. 

In his book Resilience, Eric Greitens paints the picture: 

At the age of thirty-two, he experienced a religious conversion and was baptized. But it was not until two years later, when his teenage son suddenly died, that he chose to give away his possessions and fully commit himself to the spiritual life. Augustine went on to write some of the world’s most profound books of theology—including the Confessions, the story of his spiritual journey and the first autobiography ever written in the West. When he reflected on all the selfish ambition he began with, and all the false starts and doubts on his path, he could only say to God, “I have loved you so late.”

I hope you choose to love God early. 

I love you.
