Proverbs 3:5-6,
"Trust in the LORD with all thine heart;and lean unto thine own understanding. In all thy ways acknowledge him,and he shall direct thy path"
To trust means to rely on somebody. To vouch on a person that he is going to do what you expect from him. Before you can trust a fellow, your relationship would have gone beyond extra ordinary, you would have been so close that even your 100% assurance will be seen in you over the person. But do you know,it is dangerous to trust a person,they don't last,they may end up disappointing you at the most needed time.
In Proverbs 3:5-6,it is said that you must trust only God with everything in you. God never fails and He will not. Do not that your understanding can do a lot of things,when you do things without involving God, you will end up losing something precious to you. When you trust the Lord and involve Him in your daily activity,He will never disappoint you but will direct your path. Human being may promise and not fulfill it but when God promises,He will surely bring it to pass.
When things are going bad,you need to trust God.
When you think all hope are lost,trust God
When things are not happening the way you wish it,just trust God
When there is no help anywhere,trust God
When all roads are blocked,trust God
Even the Bible says in Luke 1:37 that "For with God,nothing shall be impossible "
A times when trusting Him,His will may be far more difficult than trying to take matter into our hands. When we trust God,we surrender all our entire life and even our future to Him. We don't know what will happen in the future but we need not to worry about anything but only trust in God that He will perfect all things according to His will.
God's plan for us is to prosper and He wants us to become great,though we may not see it now but trust Him that He is preparing something tangible for you. He is the "Alpha and Omega", He sees the end from the beginning, He knows our worth and He is busy working out the best for us. Only trust God.
An example of trusting God is in the case of Shedrach, Meshach and Abednego. I so much love and envy these people, even at the verge of throwing them in the big furnace,they said something in Daniel 3:17, "If it be so, our God whom we serve is able to deliver us from the burning fiery furnace,and he will deliver us out of thine hand, O king"
These guys so much trust in their God because they know the God they serve. God doesn't disappoint His children, when you call on Him He will surely hear and answer you. They refused to bow down to an image and at the end,they were delivered because of their trust in God
In conclusion, you also need not to worry about that conditions, only trust in God and hand over everything to Him,He will come to your aid and give you an everlasting Joy.
