Therefore thus says the Lord [to Jeremiah]: If you return [and give up this mistaken tone of distrust and despair], then I will give you again a settled place of quiet and safety, and you will be My minister; and if you separate the precious from the vile [cleansing your own heart from unworthy and unwarranted suspicions concerning God's faithfulness], you shall be My mouthpiece. (Jeremiah 15:19 - Amplified Bible)
Every relationship is built on trust, or degraded by the lack of it. The more trust you have in a relationship, the more sound the relationship is. Decrease the trust and the relationship becomes shaky. What kind of trust do you have in your relationship with God? Not sure? I'll ask a different way: How solid is your relationship with God? Your answer will depend on your level of trust in God as being your All in All.
No matter how much trust we have, it will be put to the test. Our challenge is how we function day to day when our trust is tested such that we don't allow our trust in God to wane. It is when we experience suffering - and we will experience suffering - that our trust is most important in our relationship to God. If we have little trust, then when trials come we are likely to assume God is unhappy with our "performance" or is punishing us. If we have a moderate amount of trust, we may not necessarily think God is punishing us but we may become suspicious as to whether or not God really has our best interests at heart. If we have full trust, then we are like Paul - to live is Christ but to die is gain. Or, even better, we are like Jesus in the garden - regardless of what I might want, I want what the Father wants. Full trust allows us to take whatever comes and continue to say, "It is all for His glory! He is God and I am not!"
Lord I pray we all would have full trust in you. If we have not, we repent and put our trust in You. If anyone needs help trusting You, I ask that You would help them - guide them in Your word and speak to them by Your Holy Spirit.
