Without faith, you are not pleasing to God, who insists that "...the just shall live by faith...",  and if you aren't deliberately living in a way that is pleasing to God, then you're also depriving yourself of all the wonderful things which God wants to do in your life.  You didn't begin this journey to end up nowhere, but without exercising faith (in God), you can be certain of that outcome.  And if you are going to live by faith, it may as well be "with all your heart", indeed, that's the only way this [kingdom] works.  Always remember who God is, and what he is able to do.  He's "not a man that he should lie", and "...there is nothing to hard" for him.  You can absolutely trust his word, and all of his promises are "...yes and amen", and there is no way you can "trust in the Lord with all your heart" and be disappointed  -  so, here's a challenge:  beginning today, really press into faith.  Daily digest the word, pray constantly, seek God's will in all things, show brotherly love to all, and "study to be quiet, and do your own work".  Practice regular, in person, fellowship with other believers' (Go to church!), and therein be an active, participating, supporter of that house.  These few adjustments, applied everyday (consciously/deliberately) will bring about amazing transformations in your relationship with God, and therefore, your life!  Your Kingdom life is a fantastic journey of faith, with an engrossing storyline and an incredible finish, God has promised, and if you can only believe, you will see amazing things, by faith.
