Messages of Faith 🙏✨
Be Comfortable in Whom Jesus Made You
Meditating on 1 Samuel 17:39 where David refuses Saul's armor. A reflection on embracing your God-given identity and anointing rather than trying to be like others when facing life's challenges.
Defying You Means Defying the Holy Spirit
Meditating on 1 Samuel 17:10,26 about Goliath defying Israel's armies. A reflection on how when the world comes against believers, they're actually defying the Holy Spirit who lives within us.
God Used the Law Back on the Devil
Meditating on 1 Samuel 17:50 and David's victory over Goliath. A reflection on how Jesus uses the Law back on those who condemn Christians, delivering us from condemnation through His grace and righteousness.
Jesus Multiplies the Little You Give to Him
Meditating on John 6:9-10,13 and Jesus feeding the five thousand. A reflection on how Jesus multiplies the little we give Him through tithing, sowing, and Holy Communion - turning small seeds into great blessings.
