Romans 14:5,6 (KJV)
5 One man esteemeth one day above another: another esteemeth every day alike . Let every man be fully persuaded in his own mind.
6 He that regardeth the day, regardeth it unto the Lord; and he that regardeth not the day, to the Lord he doth not regard it . He that eateth, eateth to the Lord, for he giveth God thanks; and he that eateth not, to the Lord he eateth not, and giveth God thanks.
Be vigilant and stay in God's will. Seek His hand and allow His righteousness to flow inside of you.
Don't let people fool you into thinking that you can just live in sin and be all right with God, but come to Jesus and repent.
The Holy Spirit is our guide but is unable to lead us if we are living in the world and sin has a hold of our lives.
