Trust is of great significance due to the fact that it involves a person’s credibility, character, along with ability to be relied on. With that being the case, the intrinsic mechanism of trust is that it reveres whom a person is. Conversely, a person cannot be felt honored when he cannot be trusted.
Let’s put it that way, if as followers of Christ, you’ve doing your very best by allowing God to work through you through His Spirit in order to transform you into the person that He wants you to be and for whatever reason someone whom you know so well cannot trust you with something, there’s no doubt about the fact that would hurt. The reason is that you’d feel like you’re let down by that individual’s ignorance and distrust.
So to a much greater degree, the same concept also applies to God. Given the fact that He’s a God who has an uncompromising integrity in certainly everything. God is deeply troubled when we cannot trust Him with our life’s problems. Our unbelief or lack of trust is equivalent to us telling Him that He cannot be trusted regardless of whom He claims Himself to be.
Trust is the essence of our relationship with God. Trust and faith are pretty much the same thing. And we’re told that God cannot be pleased without faith according to (Hebrews 11:6). Trusting Him means relying on Him and His ability to provide.
Furthermore, trusting Him means embracing completely whom He has claimed Himself to be in His infallible Word. So we have to take His Word at face value by letting it decide how we should react when things are not going well for us.
Bear in mind, faith and trust are pretty much the exact same thing. He wants us to rely on Him without reservation since He’s the only One is fully capable of meeting all our needs. See without faith it is impossible to please God.
