Jesus said love God with all your heart and soul and strength, how? I can't see God, I can't hear his voice. Is it by reading the Bible because I did read some of the stories and changes to my heart.
Pick something you love. Not something you like a lot, but something/someone that you would die to protect, thats love. That being said, you dont need to protect God, He is all powerful, and He subdues His own power with us out of love for us and that would would repent and turn more fully towards Him. But you "can" help protect those He loves here on earth.
First, by not being a hypocrite, being an example that others see the truth in, even if they dont tell you so. Dont give the sheep reason to turn away from God when they see you and know you are a child of God.
Second, when you love someone, you want to know more about them, spend more time with them. Do the same to God, if you love Him, spend more time in prayer, not the prayers of those in church that want to be looked on as spiritual, but the prayers/talking your mind to God about life, what you like, what you dont like, let Him know what you appreciate in life. Dont take God for granted, He gave us this beautiful world because He loves us, tell Him you appreciate the good things in life that He provided. Spend more time learning about God, read scripture, try to learn the nature of God and how He acts or his messengers act to learn more about God.
Third and last of all, understand that He left the Holy Spirit to guide us in all things. You can mind speak to the Holy Spirit as well, ask for guidance, thats what the Holy Spirit is for. The Holy Spirit is God's representative here on earth, learn about how the Holy Spirit works, and utilize that connection daily.
