Do you want to obey God? If yes, than
"Do not be anxious about anything, but in every situation, by prayer and petition, with thanksgiving, present your requests to God. And the peace of God, which transcends all understanding, will guard your hearts and your minds in Christ Jesus." (Philippians 4:6-7).
What is the commands of God?
Love God and love others as yourself. And also - trust in God and His Son Jesus.
Never rely on ourselves but only on Jesus.
Love God and love others! God never commanded us to be good and earn His forgiveness, His love, grace and mercy, instead He said may we trust in Him, for when we are His children, than it is He who works in us so that we are enabled to love and to do the works which He Himself has prepared for us. He commands us to trust in Him every single moment of our life.
And so God commands us do not worry, instead pray for everything. We must pray not only in times of distress, need and tribulations, but constantly, about all and every thing. Without prayer (sincere talking to Him) our minds can be polluted with worldly things so that we lose our peace and therefore put ourselves in danger to be captured by the deceitfulness of things which belongs to the evil world but not the Christian who now is a new creation and lives by the truth given from God. Deep peace is available only if we put all our worries, events, circumstances, deeds etc. into His hands. His Spirit comes and dwells in our hearts producing joy, love and peace which world is not capable even to grasp. By having peace in each and every situation we are light in the dark world, manifesting our Saviour Jesus. Do not ever allow Satan to deceive you because He is a father of lies, he is deceiver and killer. Trust in the Word from God and trust in Jesus. Speak God's Word over your life and bless Him who is able to bless you more as you even can imagine so that you have His peace in each and every situation. For He works all things out for good for those who love Him, and trust in Him. And the peace of God by the Holy Spirit will guard your hearts and minds in your Saviour Messiah.
It is not possible to trust in God a little bit and the rest try to manage on own - that is disobedience. It is not possible to trust in God very much but still something try to manage on own - it is disobedience. Trust in God must be full. When you will learn that, you will experience that every His Word and promise are true, and you will receive the greatest vistory ever over all aspects of your life, and His peace will overtake you so that all the other people around you will be blessed by that.
Do not worry about anything but instead pray about everything. God knows all about you and your situation and He will go before you, He will level the mountains, He will cut through bars of iron, He will open doors before you so that it will not be shut, He will give you the riches of darkness, He will restore your life to the full. Just trust in Him and pray.
Peace I leave with you; my peace I give you. I do not give to you as the world gives. Do not let your hearts be troubled and do not be afraid."(John 14:27).
