One major aspect of faith is that it compels us to act out on it to obediently and earnestly follow whatever command God has given us if we truly want to exercise it. In fact, our willingness to act out on our faith is precisely what will demonstrate whether our faith in God is real. Our love for God can only be expressed through the means of our obedience to Him in relation to our faith in Him. With that being said, love isn’t based that much on what we say or the deep feeling of affection that we hold, but rather on the disposition of our heart to make sacrifices in order to express it.
Living for God implies having an intimate relationship with Him through Christ. In fact, that’s the foremost reason that we’re made for unlike other creations. Having said that, trust is the essence of relationship. The point is that there cannot be any relationship without at least some level of trust. But, the matter gets really complicated with respect to our relationship with God because He’s asking us to trust Him in such a manner that compels us to rise above our own human understanding, conception, weaknesses, reasoning, emotions, and feelings. In other words, the very things that are counterproductive to faith.
