God does speak to our hearts by the Holy Spirit, very gently leading us to him, not rushing or forcing us. Loving and trusting Jesus involves a full hearted life of commitment. For example, if we truly love a person enough to marry them, we wouldn't give them half our heart. Following Jesus is definitely worth it and I wouldn't want to give him less than my full commitment and love, given all he has done for me on the cross, sacrificing his whole life, to save me. Therefore I cannot give him less, as he gave me His best.
I don't describe him as a higher power. Higher power could mean any entity out there, so that's why I like to be specific when referring to my God. I do believe in God, not some god or just any god. Nice post and very interesting.
