James 4:4No man can serve two masters: for either he will hate the one, and love the other; or else he will hold to the one, and despise the other. Ye cannot serve God and mammon. Matt. 6:24 A double minded man is unstable in all his ways. James 1:8 Love the Lord thy God with ALL thy heart, and with ALL thy soul, and with ALL thy mind, and with ALL thy strength: Mark 12:30
