A lot of times things don't go as planned, but that's where faith comes. You don't need to let anxiety or fear or doubt or worry consume our thoughts. Through Jesus you have power to defeat the negativities that plague your mind. There is power in the name of Jesus. Just ask.
For God has not given us a spirit of fear, but of power and of love and of a sound mind. (II Timothy 1:7 NKJV)
