Tried many times, didnt work.
Trusting in God means trusting in Him, even when all seems to have gone wrong.
During the most difficult periods of your life, that is when God is nearest to you. He will never forsake you. You may forsake Him, but He will never forsake you, because He loves you.
Take Job for example. all the bad things that happened to him. Things were so bad that his own wife said to him, "Curse God and die." (Job 2:9) But he replied, "Shall we indeed accept good from God and not accept adversity?" (Job 2:10) Trusting in God is not always easy. You must trust God, without any conditions,
"Though he slay me, yet will I trust in him." (Job 13:15)
Remember, God has not promised us as Christians an easy life. Quite the opposite in fact. The Bible says, "The servant is not greater than his lord. If they have persecuted me, they will also persecute you." (John 15:20)
Trust and Faith in God is not something that you achieve in a second. Faith takes time to grow.
Do you want to know my reason for believing in God? I believe in God because I have seen His creation. Take the human body. It is designed to perfection. If I am hurt, my body will work to heal itself, automatically repairing the damage, with no need of instructions from me. In my opinion, something so perfect could only be designed by God.
The Bible says, "The heavens declare the glory of God; and the firmament sheweth his handywork." (Psalm 19:1) Take a sunset or a sunrise. No two are alike. Every day, a unique work of art and perfection by God. I could go on, but I think you get the idea.
Have faith in God, my friend, because He loves you, and because He knows what is best for you.
As I said before,
it comes down to this, either you believe in God and trust that He knows what is best for you, or you do not. It is that simple.
Trust in God, my friend. I am praying for you!
