Anxiety is nothing more than a battle between you and your faith in God. Too many of us, including myself at times, do not want to surrender to God in full trust during moments of despair.
God understands our troubles and will not allow us to be tempted in more than we can handle. God allows temporary periods of trials in order to teach us something or to warn us of something we need to know.
God is in full command of those who surrender to him through Jesus. Trials will always come, but getting through these difficult times takes faith In Christ.
Cast your cares on the LORD and He will sustain you; he will never let the righteous be shaken (Psalm 55:22)
