Exercising choices according to knowledge of God's word in us
1Tim.2:3 For this is good and acceptable in the sight of God our Saviour; [4] Who will have all men to be saved, and to come unto the knowledge of the truth.
Many people ask daily what God's will for them is, whether it be for the day, for certain events, or for their life. God has already revealed his will in his word. He wants all men to be saved and come to a knowledge of the truth. It's really as simple as that. If you are saved, God desires that you get into his word and study it so that you can grow in knowledge of it. The word of God fills you with his Spirit (Jn.6:63) and will bring you to a deeper understanding of his will, his ways, his judgements, and his great plan of redemption for all of creation.
But what about my questions, like should I take that job, or should I marry that person, or should I invest that money? Well, as you grow in faith and mature in God's word, you will start to make your own decisions as you grow in understanding and judgement. The word of God gives you wisdom and embeds in you the reasoning and judgements of God so that you can make your own choices in the issues of life. Children need adults to reason, judge, and decide for them, but as we mature in spirit and become more like the image of Jesus Christ, like sons, we can start to make judgements and reasoning for ourselves. God wants us to grow up and he desires us to make our own choices based on our knowledge of him and his ways.
