Today at church they were doing a teaching from the book of Daniel.
This is what I took from it and needed to hear; God was with Daniel and the other hebrew men when they were placed in the burning furnance, Jesus was seen in there with them.
Just like how Jesus was with Daniel, Shadrack,Meschack and Abednigo, He'll be with us to during times of fire (hard times). We'll go through tough times but God will go through them with us and takes us out unharmed and unburnt just like how the Hebrew men were not burnt by the fire.
Also in terms of purity, we must be like Daniel and refuse to conform to the world we live in, they were put into the burning furnance because they refused to bow down to an Idol.
When they had to face fire because of obeying God, God took them out and promoted them to a greater level.
Love is an action, we can show God we love him by living for him and not ourselves and this is what the Hebrew men did.
