First a person needs to recognize that he is a sinner, accept Jesus as his savior and renounce his own will to do God's will (Matthew 16:24). When God accepts this dear one into sonship, he is spirit begotten. God's spirit will slowly transform him into Christ-likeness. How does this happen? Romans 12:2 (NLT), "Don’t copy the behavior and customs of this world, but let God transform you into a new person by changing the way you think. Then you will learn to know God’s will for you, which is good and pleasing and perfect." Disobeying God's will becomes painful and he seeks forgiveness to restore his close relationship with God. He sets his affections on things above and doesn't strive after earthly riches, status, power, etc. (See Matthew 6:19, 20.) He learns to love righteousness and hate wickedness (Hebrews 1:9).

Another evidence of spirit begettal is answered prayer. A Christian will petition God for help and God will answer him. (Always remember to include in your requests, "Not my will but thy will be done" Luke 22:42.) Sometimes God answers yes, sometimes no, and sometimes wait. The answers may seems like coincidences but one wise man said: "Answers may seem like coincidences, but when I stop praying, the 'coincidences' stop happening." 

However, it is also possible for a Christian to ignore God's word. The apostle Paul warns,  "Do not quench the spirit" 1 Thessalonians 5:19 (ESV). This means a man can ignore those little prompts to do God's will and harden his heart. He may think that a little waywardness is not that important. It's just a small thing. Song of Solomon 2:15 warns, "Take us the foxes, the little foxes, that spoil the vines." These foxes represent those little compromises and sins a person may commit daily. But these sins actually can spoil his walk with God. Remember, "He who is faithful in very little things is faithful also in much…" Luke 16:10 (ESV).

God loves His children so much that “even the very hairs of your head are all numbered…” Luke 12:7. Therefore, be “…confident of this very thing, that He who has begun a good work in you will complete it…” Philippians 1:6 (NKJV)
