For God has not given us a spirit of fear, but of power and of love and a sound mind. 2 Timothy 1:7
This verse makes it clear that the fear comes from the devil, but God gives us power, love, and brains (for sure power and love). As we get older, the fear thing can really take over if we let it. Day to day living is challenging, and we can fear some of the most simple things in life!
But, even though we have to fight the fear, the power and love can overflow. God wants us to feel His love and take His power each day. Life is NEVER easy, but it is doable because we have such a loving Father. We have to ask Him for that power. It is so there if we seek it.
As for me I am still working on the sound mind, and God is still working on me!
