We have to fight to keep our minds stayed on the word of God and on his promises. There are many voices within our culture and society ready to challenge our faith and belief system. Academics, science and intellectualism often stands squarely opposed to our belief system. It takes a made up mind to remain in faith and a mind daily renewed by the word of God. People are often ready to tell you what is possible and what is practical or realistic.
The decision to live a life of faith means doing what God says and this will not always make sense to everyone. Ask Noah about being told to build an ark when there was no water. (Genesis 5) We can also refer to Mary who was told to expect a child when she was still a virgin and Joseph who was convinced to marry her although he knew the child was not his. (Luke 1:26-48; Matthew 1:18-25)
My advice is to not waste any time trying to explain things related to faith to people who refuse to have faith. “Have nothing to do with foolish, ignorant controversies; you know that they breed quarrels.” (2 Timothy 2:23) Even people who call themselves Christians can have contrary ideas about what God says. We see this in the story of the young prophet who was given specific instructions from God. Along came an old prophet who gave him contradictory ideas and who also later told him that he would die because he listened to what he said. (1 Kings 13:11-25)
Let us stay in faith, listen to the word of God and seek spiritual wisdom and focus on what God says over what other people say. “It is better to trust in the Lord than to put confidence in man.” (Psalms 118:8)
