Scriptures tell us that we should not be unequally yoked. Unfortunately many Christian men are not truly Christian, but rather simply think or believe they are. How much time do they spend every day in prayer and reading scripture? Do they know Yeshua? Have they met Him?
John 14:21 Whoever has my commandments and *keeps them,* he it is who loves me. And he who loves me will be loved by my Father, and *I will love him and manifest myself to him.*
Most Christians don't even keep the Fourth Commandment.
Exo 20:8-11 Remember the sabbath day, to keep it holy. Six days shall you labor, and do all your work: but the seventh day is the sabbath of the LORD your God: in it you shall not do any work, you, your son, your daughter, your manservant, nor your maidservant, nor your cattle, nor the stranger that is within thy gates: For in six days the LORD made heaven and earth, the sea, and all that in them is, and rested the seventh day: therefore the LORD blessed the sabbath day, and hallowed it.
Exo 31:13 ...Above all you shall keep my Sabbaths, for this is a sign between me and you throughout your generations, that you may know that I, the LORD, sanctify you.
Heb 4:9-10 So then, there remains a Sabbath rest for the people of God, for whoever has entered God's rest has also rested from his works as God did from his.
