Perhaps the following illustration will help.
Imagine you've been sick for many months and no doctor has been able to help you. No one has been able to even identify the problem. You give up on doctors; but one day you're feeling so awful you decide to go and see another doctor. This doctor says, "I know exactly what you have. Take one of these tablets every morning and night for a week, and within two weeks you'll have regained your strength and you'll feel as good as you did before." But you're sceptical. You think the doctor is wrong. But because you're feeling awful, and you've got nothing to lose, you decide to take the doctor at his word and do what he says. You've decided to trust him even though you don't believe him. After a week of taking the tablets you're still feeling a bit weak, but you're feeling a lot better. By the end of the second week you've regained your strength, and you feel just as good as you did before the illness.
Do you think it will be hard to trust this doctor in the future? No, because now you have begun to believe in him. Jesus said, "The work of God is this, to believe in the one he has sent." If you take Jesus at his word you will worry less and less about yourself. If you dare to do what he says, you will come to believe in him. And the more you trust him the more you will believe in him. He is the only one who is worthy of our complete trust. Trust Jesus and you will come to know him; then his love will flow into you and out from you.
It is not hard to trust God--though it can be frightening. He tells us not to worry because he loves us. When we worry we take matters into our own hands, and that's when we make a mess of things. God has our best interests at heart. Nothing can separate us from the one who is love. Nothing can separate us from the one who is life.
...neither death nor life, neither angels nor demons, neither the present nor the future, nor any powers, neither height nor depth, nor anything else in all creation, will be able to separate us from the love of God that is in Christ Jesus our Lord. (The Bible)
The King of this world is worthy of our trust because only he knows us perfectly, and only he loves us perfectly.
Yes, he often asks us to do things which seem dull and boring. There's often no intimacy with people in working hard or in doing a good job, but it's those kinds of things that make intimacy possible. The more trustworthy we are the more we will be trusted. The more we trust Jesus the more others will trust us. (And though in the doing the things God asks us to do there is often no intimacy with people, there is intimacy with God when we trust him.) Trust Jesus, he knows what he's talking about. He can fill you with hope for this life and the next.
"But what if I have to go against my conscience to do what Jesus asks of me?"
We do not have to go against our conscience to trust him. If we read the Bible and listen closely, we will usually know what to do. What do I mean by listen closely? In the poem "Willie's Question" a father explains to his son how to listen and hear God's voice. (That is how to love God with one's mind.)
“Let anyone who is thirsty come to me and drink. Whoever believes in me, as Scripture has said, rivers of living water will flow from within them.” (Jesus, from the Gospel of John).
"Taste and see that the Lord is good" (King David, from Pslam 34).
