Problems arising is inevitable, but how we react towards it is what matters. Fear and doubt are the tools the enemy uses to hold people down. Fear is not of God. Whenever we are tensed in certain situations the outcome in most cases would be a bad one. The world we live in provides us almost everyday with one thing or the other to worry about.
Ps.121.1 & 2I will lift up mine eyes unto the hills, from whence cometh my help. My help cometh from the LORD, which made heaven and earth.
The worst choice we can make is to put our hope in man. If where we place our hope is on man then we may end up being disappointed. But when we put our full trust in God we shouldn't have any cause for alarm or to work ourselves up. No matter our big our problems may seem in our eyes it is merely a minor issue to God.
Philippians 4.19 - But my God shall supply all your need according to his riches in glory by Christ Jesus.
Whatever we are hoping for God is more than able to bring it to manifestation. God is the best assurance we can ever get. So instead of brooding on the problems we should hand it over to God.
