Like every seed there needs to be some nurturing and care, otherwise it gets out of hand and grows wildly. Just like as a human being, if your guardian is not there to help grow, develop, and mature you, you can end up with depression, low self esteem, lack of discipline, anger issues, etc.
The same can be said for your spiritual life. Failure to nurture your spiritual life leads you to a faithless faith. 1 John 3:9 says, No one born of God makes a practice of sinning, for God’s seed abides in him, and he cannot keep on sinning because he has been born of God. When the pure and incorruptible seed of God begins to germinate its grace, your new nature cannot be destroyed, or encouraged by sin. Instead, as your life begins to abide by the word of God, that seed becomes a defense mechanism, or antidote and opposes sin.
Continue to grow in Christ. Continue to read, pray, and fast. You need to develop that seed inside you. If you aren't, you are tying God's hands. This may be your season to turn the TV off and spend time with the Lord.
