Difficult circumstances are only a reminder of how much we need to lean on God's grace and goodness, because even when things are going well, we are no less in need of divine intervention. God is responsible for every breath that we take and every beat of our heart, and this rythmn ought to beat in our soul as a reminder of our constant need for Him - and our thankfulness to Him.
If you are someone who has committed their life to God by embracing the gift of His son, Jesus Christ, you are not in control of your own life. However, you can rejoice in the fact your life is secure in the hands of Almighty God - for eternity.
If you are someone who remains on the outside, keeping your distance from God and holding back from committing your life to Christ, you don't retain control - your life is out of control. And the only certainty in your uncertain future is that this condition threatens to separate you from God - for eternity.
For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life. For God did not send his Son into the world to condemn the world, but in order that the world might be saved through him. Whoever believes in him is not condemned, but whoever does not believe is condemned already, because he has not believed in the name of the only Son of God.
