Do not trust your feelings. They change. Stand on God's promises. They never change. After you are saved, there are three things to practice daily for spiritual growth:
Pray -- you talk to God.
Read your Bible -- God talks to you.
Witness -- you talk for God.
You should be baptized in obedience to the Lord Jesus Christ as a public testimony of your salvation, and then unite with a Bible-believing church without delay. "Be not thou therefore ashamed of the testimony of our Lord . . . ." (2 Timothy 1:8). Join and attend a local Bible believing church.
"Whosoever therefore shall confess [testify of] Me before men, him will I confess also before My Father which is in heaven" (Matthew 10:32).
