I think that this sentence could be easily misinterpreted, so I want to clear that up first. I don’t think she means to say that if God doesn’t respond to our obedience that somehow it’s his fault. I think what she is getting at is that if we walk in obedience, we can trust God for the fruits of that obedience.
For me, this has profound implications. Why? Well, I tend to worry about the outcomes of the decisions that I make. Many times, my decision-making becomes confusing because I try to predict what the outcome will be beforehand. (Yes, there are some decisions in which it is wise to seek many counselors and to consider all the possible outcomes, and even count the costs. But when we count the cost of obedience, we must trust that the favor of God in obedience is far greater gain than anything else we might have gained through disobedience. )
An example of this in my life is that often times, although I sense a strong urging to encourage someone with scripture or truth, I will not do it because I fear that it will be taken the wrong way. “What if they think I think I am better than them? What if they will just think it is silly? What if this and that and this and that?” Many of these concerns muffle the clarity of my calling according to Scripture.
But how different would our lives look if we really did trust and obey? What if we listened to the Spirit of God, obeyed the word of God, and didn’t worry about the things that we so often worry about. What if we didn’t worry about how other people will perceive what we are doing? What if we didn’t worry about how obedience might affect our relationships with other people? Maybe then we would share the gospel with unbelievers, not fearing that they will think we are weirdo Bible-beaters. Maybe then we would hold our Christian brothers and sisters accountable, not fearing that our relationship might be severed. Maybe then we will humbly receive rebuke, criticism, or instruction, not fearing that we might seem incompetent for doing so. Surely we would be much more concerned with God and the advance of his Kingdom than we are with what others might think.
It comes down to this: who is it that we fear? Fear of God, trust in God, and obedience to God are inextricably linked throughout the entire word of God. We obey Him because we trust that He is who He says He is and that He will do what He says He will do (fear). The rest is up to God.
Look at Psalm 34:7-10, and see the promises God makes to the one who fears him!
“The angel of the LORD encamps around those who fear Him, and rescues them. O taste and see that the LORD is good; How blessed is the man who takes refuge in Him! O fear the LORD, you His saints; For to those who fear Him there is no want. The young lions do lack and suffer hunger; But they who seek the LORD shall not be in want of any good thing.”
Now may we look exclusively to HIM, and let our lives be marked by a unique desire to please HIM alone! We will not be put to shame because God’s love has been poured into our hearts through the Holy Spirit (Rom 5:6).
