The following are some principles from God's Word that will help you to discern what God's will is for you.
1. God does have great plans for your life.
We were created by God, in His image, for a purpose. Just as God set apart from birth Isaiah (Isaiah 49:1), Jeremiah (Jeremiah 1:5) and Paul (Galatians 1:15) for a specific purpose, he also has a specific plan for your life.
"For I know the thoughts that I think toward you, saith the Lord, thoughts of peace, and not of evil, to give you an expected end." (Jeremiah 29:11)
The Bible says that God's will is "good, acceptable and perfect." (Romans 12:2)
2. God's will, first and foremost, is that we have a relationship with Him through His Son, Jesus Christ.
"For this is good and acceptable in the sight of God our Saviour; Who will have all men to be saved, and to come unto the knowledge of the truth." (1 Timothy 2:3-4)
3. God wants us to be Christ's disciples.
This means Christians must be committed to following God's will daily, whatever the cost.
"And he said to them all, If any man will come after me, let him deny himself, and take up his cross daily, and follow me." (Luke 9:23)
4. The Bible will help us to know God's will.
"Thy word is a lamp unto my feet, and a light unto my path." (Psalm 119:105)
5. God promises to give us wisdom if we just ask Him in prayer, believing that He will give it.
Sometimes we need to just ask God to give us wisdom to discern His will.
"If any of you lack wisdom, let him ask of God, that giveth to all men liberally, and upbraideth not; and it shall be given him." (James 1:5)
In Philippians 4:6, God tells us that we should pray about everything.
6. God has given us the Holy Spirit for guidance.
"...when he, the Spirit of truth, is come, he will guide you into all truth..." (John 16:13)
7. We should listen to the advice of godly men and women that God has placed in our lives.
Many times the advice of a parent, pastor, youth minister, Sunday School teacher or other mature person is just what we need to hear to help us decide what God wants us to do.
"The way of a fool is right in his own eyes: but he that hearkeneth unto counsel is wise." (Proverbs 12:15)
"Without counsel purposes are disappointed: but in the multitude of counsellors they are established." (Proverbs 15:22)
8. The Bible says that there is a peace that comes when we are pleasing God with our lives.
When deciding between two alternatives that you have been praying about, sometimes one of the options will give you a greater peace. That option is probably God's will.
"And the work of righteousness shall be peace; and the effect of righteousness quietness and assurance for ever." (Isaiah 32:17)
9. We should trust God in faith that He will accomplish His will in our lives.
"Trust in the Lord with all thine heart; and lean not unto thine own understanding. In all thy ways acknowledge him, and he shall direct thy paths." (Proverbs 3:5-6)
"Being confident of this very thing, that he which hath begun a good work in you will perform it until the day of Jesus Christ:" (Philippians 1:6)
10. God has given each of us gifts and abilities to use in His service.
God always equips us to do what he calls us to do. If you aren't gifted in a certain area, God is probably not calling you to minister in that area. (see Romans 12:6-8, 1 Corinthians 12:1-11 and Ephesians 4:11-13 for lists of spiritual gifts.)
Remember that God's ultimate purpose for all of us is that He would be glorified (1 Corinthians 10:31) and that the gospel and God's kingdom would be advanced (Genesis 50:20 and Philippians 1:12).
